A dozen people were injured after two subway trains collided in a tunnel in Rome on Friday morning, the Italian Red Cross said.
The collision happened near the EUR Palasport station in the south of the city, the Red Cross said via its Twitter account.
Two people were trapped after the incident and had to be rescued by firefighters, local newspapers reported. Others were taken to hospital to be treated for minor injuries.
Guido Improta, Rome’s head of city transport, told Italy's state-run broadcaster RAI that he believed the collision was down to "human error."
A photo by the Italian news agency ANSA showed an injured person being carried out on a stretcher.
