The explosions occurred during the morning rush hour, targeting a busy commuter rail line that runs just south of downtown Madrid. Four bombs (planted at the front, middle and rear of a single train) exploded at 7:39 at Atocha station, and three bombs planted on a single train went off simultaneously just outside of Téllez street, near Atocha station. Two more bombs on one train detonated at 7:41 at El Pozo del Tío Raimundo station. One further bomb exploded on a train at Santa Eugenia station at 7:42. Most of the casualties occurred at Atocha/Téllez (89 confirmed dead) and El Pozo (70) with another 17 at Santa Eugenia.
