On the 11th March 2004 various bombs were detonated on commuter trains in Madrid, killing 200 people and injuring around 2000 as they were on their way to work. This resulted in a surprise result at the elections held a few days later.
Today, almost three years later, the authors of this bombing are still unknown, the investigation held by many to be a farce (34 of the accused were police informers), senior policemen have been charged with tampering with evidence after a newspaper investigation. The only thing known for sure is that it was not 'Al Qaeda'.
In many towns and villages, rallies are held every month on the 11th to protest this situation and the apparent intent of the government to cover up what really happened.
This is the first of such rallies held in my village. The banner reads "11-M (L)ies and Manipulation" - We want to know!"
