The March 2004 Madrid train bombings were not suicide bombings (see 7:37-7:42 a.m., March 11, 2004), and most of the key bombers remain in Spain, holed up in an apartment in the town of Leganes, near Madrid. By April 3, 2004, Spanish police are tipped off about the general location of the apartment from monitoring cell phone calls. Agents from the Spanish intelligence agency, the UCI, arrive near the apartment around 2:00 p.m. The head of the UCI unit on the scene will later say that he is told around this time that the specific floor where the suspects are has been pinpointed through phone intercepts, but he will not recall who tells him this. At about 5:00 p.m., one of the suspected bombers, Abdelmajid Boucher, goes outside to throw away the trash. He spots the plainclothes agents surrounding the house and runs away. The agents pursue him but he gets away. Presumably, he soon calls the other men in the apartment to let them know the police are outside. A gunfight breaks out between the police and the men in the apartment. [El Mundo (Madrid), 3/21/2007; El Mundo (Madrid), 3/21/2007] During the several hours of shooting, the bombers make a series of phone calls to relatives, telling them good-bye. They also allegedly somehow call radical imam Abu Qatada three times, even though he is being held in a maximum security prison in Britain, and get religious approval for their planned suicides (see Between 6:00 and 9:00 p.m., April 3, 2004). When police assault the apartment shortly after 9:00 p.m. that evening, the seven bombers still there are reportedly huddled together and blow themselves up (see 9:05 p.m., April 3, 2004). [New Yorker, 7/26/2004; Irujo, 2005, pp. 360-361] In late 2005, Boucher will be arrested while traveling through Serbia by train. He will be extradited to Spain and sentenced to 18 years in prison (see October 31, 2007). [Washington Post, 12/1/2005]
