At least 30 people were killed when two high-speed trains collided in Spain on Wednesday, the second deadly accident in less than a year on the line connecting Madrid to the southern Andalusia region, regional authorities said.

Footage from regional Castilla-La Mancha television showed a derailed train with several carriages remaining on an elevated section of track while twisted metal, broken panels and wreckage could be seen strewn across an embankment beneath the line.

Miguel, a passenger traveling with several colleagues in the rear ?car of one of the trains, described to COPE radio the moment of the accident.
