Two-dozen people were injured, one of them seriously, when two trains collided Wednesday in the Cuban capital, state television said.

A freight train headed west toward Pinar del Rio and an eastbound passenger train plowed into each other near the campus of Jose Antonio Echeverria University.

The injured were taken to four different hospitals in the capital, state television said, adding that authorities had already begun an investigation to determine the cause of the crash.

Nineteen people died and 149 others were hurt last year in 106 separate accidents on Cuban railways, according to official reports acknowledging an increase in such incidents in recent years.

Most of last year's accidents involved trains' running over cattle or people or collisions with vehicles at level crossings.
