One person was killed and around 40 injured, including one in a critical condition, when a tram derailed in central Milan on Friday, a spokesperson for local firefighters said.
The tram, one of the newest models in operation in Milan, came off the tracks in Vittorio Veneto street, one of the city's key downtown corridors, crashing into the window of a shop, the spokesperson Vittorio Di Giacomo told Reuters.
Local emergency services said 13 ambulances were on the scene.
Civil protection teams set up a tent to assist the injured, according to a Reuters eyewitness.
The Milan transport company, ATM, said in a statement it was "deeply shocked" by the accident, expressed its sympathy to all those affected and said it was working with judicial authorities to try to understand what caused it.
