The Al-Kifah Refugee Center in Brooklyn, New York, is al-Qaeda’s main foothold in the US and most of the 1993 WTC bombers are closely tied to it. It had been formed in the 1980s to send militants to fight in Afghanistan and also help veteran fighters settle in the US (see 1986-1993). But the Afghanistan war against the Soviets ended in early 1989 and the winning factions soon began fighting amongst themselves (see February 15, 1989). But a new cause is on the horizon as Yugoslavia starts falling apart. By 1991, the center’s parent organization in Pakistan, Maktab al-Khidamat(MAK)/Al-Kifah begins setting up al-Qaeda charity fronts in the Bosnia region (see 1991). The main regional MAK/Al-Kifah branch in Zagreb, Croatia, is also called the Al-Kifah Refugee Center like the Brooklyn branch and has very close ties with that branch (see Early 1990s). In 1992, war breaks out in Bosnia (see April 6, 1992) and the Al-Kifah Refugee Center in Brooklyn shifts its focus fully to the Bosnia cause. For instance, the Boston branch publishes “A Call for Jihad in Bosnia.” It claims that more than 100,000 Bosnians had been killed and that thousands of Muslim girls had been kidnapped and kept in Yugoslav army camps for sex. It urges readers who wish “to provide the emerging jihad movement in Bosnia with more than food and shelter” to send their donations to Al-Kifah. And just as Al-Kifah led the effort to send US-based militants to fight in Afghanistan, it appears to do the same for Bosnia. Vanity Fair will later claim, “Dozens and perhaps hundreds of US residents are reported to have joined appeals to fight the Serbs in Bosnia.” [Vanity Fair, 3/2005] The head of the Al-Kifah Refugee Center’s Zagreb branch, Kamer Eddine Kherbane, apparently is also one of the leaders of the mujaheddin fighters in Bosnia around this time (see 1990 and 1991). The CIA had ties to Al-Kifah during the Afghan war (see Late 1980s and After) and there is some circumstantial evidence of US government ties to it during the Bosnia war. In 1992, Ali Mohamed, a double agent and ex-US Special Forces officer with close ties to Al-Kifah, leads a group of US militants who are all ex-US soldiers to train and fight in Bosnia (see December 1992). Abu Ubaidah Yahya, an ex-US marine and security chief at the Brooklyn branch, will lead a second group of US militants to fight in Bosnia (see Spring 1993).
