Two trains running on the Green Line in Boston have crashed into each other, injuring more than 20 people, authorities said.

The Boston Fire Department said 23 people were taken to hospitals with injuries, none of which were life threatening.

The trains crashed on the track running along Commonwealth Avenue west of Boston University.

The Massachusetts Bay Transit Authority said in a tweet around 6:15 p.m. that train service was suspended on part of the B branch of the Green Line because of an accident.
