Two trains collided in southern Italy on Tuesday, killing at least 20 people and injuring dozens, according to wire reports.
The head-on crash occurred in the region of Puglia, The Associated Press reports, and the trains belonged to a local private rail company.
The line "is used by thousands of people daily on about 200 trains," the BBC reports. "Work is under way to make it a double-track line."
Rescue work is ongoing, the AP writes, with at least two people rescued alive from the wreckage.
