Mar. 11 -- Eleven bombs exploded in commuter trains and stations in Madrid at the height of rush hour this morning killing more than 190 and wounding over 1,000, marking the deadliest terrorist attack on Spanish soil. 13 backpacks, each packed with roughly 25 pounds of the explosive Titadine were left under seats on four trains as they were entering four stations in Madrid. In a statement released shortly after the attack, Spanish Interior Minister Angel Acebes said the main focus of the investigation is the Basque separatist group ETA. The explosives used in the attack, Titadine, have been used by the group in previous attacks, and a van carrying Titadine was intercepted on February 29 when two suspected ETA members were arrested.

However, today's attacks were on a scale beyond anything ETA has done in the past. This has raised speculation as to whether ETA was in fact behind the attacks.

A new development since the morning has raised even further questions the Spanish interior minister said that another van was found this morning east of Madrid, in the town of Alcana de Henares, along the commuter route to the main train station in Madrid. The van contained seven detonators and an Arabic tape with verses from the Islamic holy book, the Quran. The disclosure fueled speculation that Islamic extremists could have been involved.
