Sanae was thirteen years old. She took the suburban train each day to Juan de la Cierva High School. She was an only child. Her parents were divorced and Sanae lived with her mother and her mother’s partner. A vigil was held for the girl at the mosque on the M-30, where she was a regular attendee. On the day after the bombings, her schoolfriends, many of them Spanish, filled the place with flowers.
11 March 2004 fell on a Thursday. Early that morning, a number of terrorists with links to Al-Qaeda planted thirteen bombs on four suburban trains covering routes running through Madrid. Ten of the bombs exploded between 7.37 and 7.39 am, when the trains were at Atocha, El Pozo and Santa Eugenia stations and alongside Calle Téllez. 191 people were killed in the attack and around 1,500 were wounded. It was the deadliest terrorist attack in Spanish history. On 3 April 2004, agents from the Special Operations Group (GEO) were about to enter an apartment in Leganés where the perpetrators of the attacks were believed to be hiding when the terrorists detonated twenty kilograms of explosives in an act of collective suicide. The ensuing blast killed one of the officers, bringing the total number of people killed by the 11 March bombers to 192.
