At least 20 killed, dozens injured as trains collide

At least 20 people died and dozens were injured when two passenger trains collided head-on in southern Italy on Tuesday, a regional official said.

The crash happened on a single stretch of track in countryside between the towns of Corato and Andria. Both trains were made up of four carriages.

An aerial image showed carriages smashed and crumpled by the force of the impact, with debris flung out among olive trees which flanked both sides of the track.
