2004 Madrid train bombings

On March 11, 2004, at 7:30 in the morning, Madrid had its worst terrorist attack. The bombers killed 191 people, most of them from Spain, and injured 1,800. The terrorists bombed four commuter lines leading to Madrid. The explosives were hidden in backpacks. Ten bombs exploded at the same time and three never were set off. Spanish authorities found the three bombs and were used as evidence to find the suspects.

The attack was planned in August 2003. The total expenses of damage cost $105,000 euro. No specific group was convicted although some groups were blamed for it. Miners who had sold explosives were arrested. Soon, controversy between the two political parties began blaming each other for distorting and hiding evidence to win the election. This all happened the three days before the main election.
