2004 Madrid attack: 20 years later, Spain pays tribute to the victims of the “11-M” Islamist attacks. Presided over by King Felipe VI and Queen Letizia, the official ceremony will begin at 12:15 p.m.

The attacks at the Atocha station, called in Spain "the 11-M", take place in a very charged political context, since the country is in the home stretch of an electoral campaign. March 11 has become the "European Day of Commemoration of the Victims of Terrorism"
