At least 30 people were killed after two trains collided on Spain's Madrid-Seville high-speed line, and the death toll is expected to rise, a spokesperson for the Castilla-La Mancha region told ABC News.

The collision occurred at around 8:30 a.m. local time at kilometer marker 118 near Urda and involved a Renfe train and an Iryo train, both traveling from Madrid to Seville, the Spain's Transport Ministry told ABC News.

As part of the preliminary investigation, authorities said the Renfe train probably struck the Iryo train from behind, causing two coaches to derail.
