According to ABC News, beginning in August 2010, the US begins flying a stealth drone over the newly discovered compound in Abbottabad, Pakistan, where intelligence experts have discovered Osama bin Laden is probably secretly hiding (see August 1, 2010). The drone is of a new type, and very little is known about it. Crucially, it is able to fly above Pakistan undetected by Pakistan’s air defenses, allowing the US to keep its interest in the town and compound a secret. [ABC News, 5/19/2011] In March 2011, a US strike force will assault the compound and kill bin Laden (see May 2, 2011).
August-September 2010: US Intelligence Increasingly Convinced Bin Laden Is at Abbottabad Compound in Pakistan
US intelligence officials come to believe more strongly that they have found Osama bin Laden. US intelligence officials have tracked al-Qaeda courier Ibrahim Saeed Ahmed (a.k.a. Abu Ahmed al-Kuwaiti) to a compound in Abbottabad, Pakistan, in August 2010 (see July 2010), and by September they are so convinced that bin Laden is hiding there that they inform President Obama about this (see September 1, 2010). Bin Laden is not directly seen by surveillance, but there are many clues suggesting he could be there: 
Most importantly, Ahmed fits the profile of an ideal courier for bin Laden, and Ahmed lives at the compound. The compound is surrounded by 12- to 18-foot high walls topped with barbed wire. However, there is no telephone or Internet in the compound. This would seem to be an unusual security precaution, but it also makes the compound hard to monitor. The compound sits on a large plot of land and is about eight times larger than the other homes in the neighborhood. The people in the compound burn their trash instead of leaving it out for collection, like the other neighbors. The main three-story building in the compound has few outside windows. Ahmed and the others known to live in the compound have no known source of wealth that could explain how they pay the expenses of running the compound. [CNN, 5/2/2011] There are no balconies, except for those covered with more high walls. Balconies are a standard feature for wealthy houses like this one in Pakistan. One neighbor will later comment: “It’s not a proper house. It’s more like a warehouse. It’s not like a home where anyone would want to live.” [Daily Telegraph, 5/3/2011]
A senior Obama administration official will later say, “When we saw the compound where the brothers lived, we were shocked by what we saw—an extraordinarily unique compound.” He adds that intelligence analysts conclude the compound was “custom-built to hide someone of significance.… Everything we saw… was perfectly consistent with what our experts expected bin Laden’s hideout to look like.” [CNN, 5/2/2011] However, according to the Associated Press, US intelligence has known about the compound “for years,” but it did not think bin Laden would live there because there were no security guards. [Associated Press, 5/2/2011] Months later, a US strike force will assault the compound and kill bin Laden (see May 2, 2011).
August 1, 2010: US Intelligence Learns Exact Location of Bin Laden’s Hideout, in Abbottabad, Pakistan
US intelligence finally learns the exact location of Osama bin Laden’s secret compound, in Abbottabad, Pakistan. [New York Times, 5/3/2011] The compound is discovered by US intelligence tracking bin Laden’s courier Ibrahim Saeed Ahmed. US intelligence was already aware of Ahmed’s general location in northwest Pakistan and was aggressively searching for him in the hopes he could show the way to bin Laden’s location (see Summer 2009). According to one account, Ahmed accepts a phone call while in Peshawar, about 120 miles from Abbottabad, and is tracked when he returns to the compound. According to another account, he accepts the call in or near the compound (see July 2010). In any case, once the compound is discovered, US intelligence begins heavily monitoring it (see August-September 2010).
August 2010-May 2, 2011: US Intelligence Intensely Monitors Bin Laden’s Abbottabad, Pakistan, Hideout
US intelligence begins intensively spying on the Abbottabad, Pakistan, compound where they strongly suspect Osama bin Laden is hiding (see August-September 2010). The compound was discovered on August 1, 2010 (see August 1, 2010). The Washington Post will later report that “virtually every category of [intelligence] collection in the US arsenal” is used, including satellite imagery and attempts to record voices inside the compound.
CIA Safehouse – The efforts include a CIA safehouse located somewhere near the compound. Abbottabad is a tourist town with pleasant weather and colonial era charm, enabling strangers to easily come and go without attracting suspicion. The CIA takes advantage of that atmosphere to send CIA operatives and informants into the town to gather information. A former US official will say, “The [main compound building] was three stories high, and you could watch it from a variety of angles.” Moving there “was his biggest mistake.” [Washington Post, 5/6/2011]
Escape Tunnel? – Analysts even study the water tables in the area in an attempt to figure out if bin Laden could have an escape tunnel. They conclude the soil is too wet to build a tunnel. [ABC News, 5/19/2011]
Intelligence Allegedly Still Lacking – The surveillance is so extensive that in December 2010, the CIA has to secretly get Congress to reallocate tens of millions of dollars within various agency budgets to help fund it. But US intelligence is allegedly unable to get a clearly identifiable picture or voice recording of bin Laden before the raid that eventually kills him. The CIA safehouse is abandoned shortly after the May 2, 2011 raid that kills bin Laden (see May 2, 2011), since it has served its purpose. [Washington Post, 5/6/2011]
Shortly After August 2010-May 2, 2011: US Intelligence Apparently Sees Bin Laden Frequently Walking Outside, but Cannot Confirm His Identity
Shortly after US intelligence begins monitoring the Abbottabad, Pakistan, compound where it suspects Osama bin Laden is hiding out (see August 1, 2010 and August 2010-May 2, 2011), a man who fits bin Laden’s description is seen walking around outside almost every day, the Washington Post’s Bob Woodward will later report. The man leaves the main compound building but stays within the compound walls to walk around a courtyard for an hour or two. Analysts eventually start calling him “the pacer.” Satellite imagery suggests the pacer has the height and gait of a tall man (and bin Laden is at least six foot four inches tall). However, the satellite imagery is reportedly not clear enough to get a good view of his face. This tall person is never seen leaving the compound. An analysis of the daily routine of this person suggests he is living there almost like a prisoner. Allegedly, CIA Director Leon Panetta tells President Obama and other top US officials that it is too risky to send in a human spy or move electronic equipment closer to confirm if the pacer is bin Laden or not. As a result, US intelligence will still not be 100 percent that bin Laden is living in the compound when US Special Forces raid it in May 2011 (see May 2, 2011). [Washington Post, 5/6/2011] The London Times will publish a later story claiming that US intelligence was aware of the type of clothes bin Laden wore before the raid (see May 23, 2011). That would support these claims about bin Laden’s walks.
September 1, 2010: President Obama Is Informed about Bin Laden’s Compound in Abbottabad; US Allies Are Not
CIA Director Leon Panetta informs President Obama that Osama bin Laden may be living in a certain compound in Pakistan that is being monitored. (Some accounts say Obama is informed in August, but most say September, and one account specifies September 1.) [Associated Press, 5/2/2011; CNN, 5/2/2011; New York Times, 5/3/2011; ABC News, 5/19/2011; Wall Street Journal, 5/23/2011] Many of Obama’s top aides are at the top secret meeting as well, including Vice President Joe Biden, Secretary of State Hillary Rodham Clinton, and Defense Secretary Robert Gates. Panetta describes the compound and the intelligence leading to it in great detail. An unnamed administration official at the meeting will later say: “It was electric.… For so long, we’d been trying to get a handle on this guy. And all of a sudden, it was like, wow, there he is.” [New York Times, 5/2/2011] The evidence is so tantalizing that the US decides not to say anything about the compound to the Pakistani government, or to even close US allies like Britain or Canada, for fear that intelligence leaks could let bin Laden slip away. [Associated Press, 5/2/2011]
October 18, 2010: Senior NATO Official Says Bin Laden Is in House in Northwest Pakistan, Protected by ISI
An unnamed senior NATO official says that Osama bin Laden is hiding in a house somewhere in northwest Pakistan. Al-Qaeda number two leader Ayman al-Zawahiri is also hiding in a house somewhere nearby, but not in the same place as bin Laden. The official says, “Nobody in al-Qaeda is living in a cave.” This person adds that al-Qaeda’s top leadership is likely living in relative comfort, protected by locals and some members of the ISI, Pakistan’s intelligence agency. Additionally, top Taliban leader Mullah Omar lives in the Pakistani cities of Quetta and Karachi. It is unknown how the NATO official would know all this, but CNN says the person has access to classified information. [CNN, 10/18/2010] When a US raid kills bin Laden in May 2011, he will be found in a house in northwest Pakistan (see May 2, 2011), and there will be accusations that the ISI must have protected him there (see May 2, 2011 and After).
Early December 2010: Some Congressional Leaders Briefed about Bin Laden Hideout Intel
Some leaders of US Congress are briefed about intelligence on Osama bin Laden’s secret compound in Abbottabad, Pakistan. Senator Dianne Feinstein (D-CA), chairperson of the Senate Intelligence Committee, will later say: “We were briefed about suspicions about the size, about the structure of the compound, about the absence of people going in or out. We were actually shown overhead long distance photos from the air and we were essentially told that there were suspicions, serious suspicions, that this may be the place where Osama bin Laden was and that there was a 24/7 oversight of this compound.” [Time, 5/3/2011] It is likely that all of the “Big 8”—the leaders of each party in the House and Senate and the top lawmakers from each party on the House and Senate intelligence committees—are informed about the intelligence. They will continue to receive periodic updates up until the raid that kills bin Laden on May 2, 2011 (see May 2, 2011). They will get calls from CIA Director Leon Panetta two days before the raid saying that the action against bin Laden is likely to take place soon. [Time, 5/3/2011; Politico, 5/3/2011]
January 2011: US Special Forces Begin Planning for Raid on Bin Laden’s Abbottabad Compound
Navy Vice Admiral William McRaven, commander of Joint Special Operations Command, meets with intelligence officials at CIA headquarters and is shown photographs and maps of Osama bin Laden’s compound in Abbottabad, Pakistan. McRaven is one of the first military officers to be told the highly classified intelligence. He begins planning options on how the US could kill or capture bin Laden (if bin Laden is in the compound). McRaven assigns an unnamed Navy captain from SEAL Team 6 to work on the options. The captain will work daily with CIA officials on the plans. McRaven and his associates will come up with three main options on how to raid the compound (see March 14, 2011). [Wall Street Journal, 5/23/2011; ABC News, 6/9/2011]
January 25, 2011: Indonesian Militant Arrest Points to Bin Laden’s Hideout in Abbottabad, Pakistan
On January 25, 2011, radical militant Umar Patek is arrested by Pakistani intelligence agents in a house in Abbottabad, Pakistan. Patek is Indonesia’s most wanted terrorist suspect at the time, because he is the only major suspect wanted for the 2002 Bali bombing who has not yet been killed or captured. The US issued a $1 million bounty on him in 2005 (see October 6, 2005 and After). Patek has $1 million in cash on him when he is arrested, and he is shot in the leg during the arrest. News of Patek’s arrest will become public in late March 2011 (see March 30, 2011). [Associated Press, 5/4/2011; Independent, 5/8/2011] The CIA worked with other countries to get Patek. But Patek stays imprisoned in Pakistan, unlike many other terrorist suspects captured in Pakistan who are deported to the US or elsewhere. [Associated Press, 3/30/2011]
Is Patek There to See to Bin Laden? – After Osama bin Laden is killed in Abbottabad in May 2011 (see May 2, 2011), an unnamed senior US counterterrorism official will say that Patek’s presence in the town “appears to have been pure coincidence” and there is no evidence that Patek was meeting with bin Laden there. However, Indonesian Defense Minister Purnomo Yusgiantoro will later say, “The information we have is that Umar Patek… was in Pakistan with his Filipino wife trying to meet Osama Bin Laden.” Indonesian counterterrorism official Chairul Akbar will further explain that Patek was there to meet bin Laden and get his “support and protection.” Akbar says that Patek “was instructed to go to Abbottabad to meet other militants.” He will also claim that Patek may have met other al-Qaeda leaders in Pakistan, but he had not yet met with bin Laden before his arrest. [Associated Press, 5/4/2011] Patek’s arrest takes place less than two miles away from where bin Laden is hiding. [Der Spiegel (Hamburg), 5/18/2011]
Link to Bin Laden’s Key Courier – The Independent will report after bin Laden’s death that Patek met with Ibrahim Saeed Ahmed (a.k.a. Abu Ahmed al-Kuwaiti), an al-Qaeda courier who is living with bin Laden in an Abbottabad compound at the time. By this time, US intelligence is intensively monitoring the compound and everyone in it (see August 2010-May 2, 2011). However, the compound is not searched by the Pakistanis during the raid that got Patek, or in the months afterward. [Independent, 5/3/2011]
Link to Another Al-Qaeda Courier – Additionally, two French men, Sharaf Deen and Zohaib Afza, are arrested in Lahore, Pakistan, on January 23, 2001. One of them was born in Pakistan and the other was a convert to Islam. A Pakistani named Tahir Shehzad is arrested with them. Investigators will later say that they trailed Shehzad from Abbottabad to Lahore, and that the French men planned to travel with Patek to Pakistan’s tribal region where many al-Qaeda leaders are hiding. Shehzad gave up Patek’s location, which led to his arrest two days later. Later press reports will call Shehzad an “alleged al-Qaeda facilitator” who worked as a clerk in the Abbottabad post office. Pakistani intelligence had Shehzad under surveillance since 2010, when he was seen in Abbottabad with an “Arab terror suspect” (see August 2010). [Associated Press, 4/14/2011; Associated Press, 4/14/2011; News (Islamabad), 5/3/2011]
Waiting in Abbottabad for Someone? – Abbottabad resident Abdul Hameed Sohail will later tell the press that his son found Patek and Patek’s wife cold and shivering in the street, and he ended up feeling sorry for them and let them stay in his house. They were given an upstairs room, and for nine days they rarely left the room or even ate the food that he left for them. Finally, Pakistani officials raided the house, shot Patek, and took him away. Sohail is not arrested. However, his son Kashif is arrested as an accomplice, and will still be in custody three months later. Patek and his wife had arrived in Pakistan five months earlier, traveling with forged passports, but it is not known where they were in Pakistan prior to Abbottabad. (Nor is it known what happens to his wife.) [Associated Press, 4/14/2011; News (Islamabad), 5/3/2011; Der Spiegel (Hamburg), 5/18/2011]
CIA Tip Off – It also will later be reported that the CIA gave key information to Pakistan about Patek being in Pakistan, which led to his arrest. It may be that the CIA gave the information that Patek had gone to Pakistan five months earlier under another name. [Associated Press, 3/30/2011] In hindsight, this is interesting since the CIA is part of the surveillance of bin Laden’s Abbottabad compound at the time, and news of Patek’s arrest could have threatened the effort to find bin Laden.
