Greece train crash: At least 36 killed in head-on collision

At least 38 people have been killed and dozens were injured after a head-on-collision between a passenger and a cargo train in Greece.

The passenger train had been travelling from Athens to the northern city of Thessaloniki, where it collided with a cargo train on its way to Larissa.

The crash happened on Tuesday night as the passenger train, with almost 350 people on board, emerged from a tunnel near the Vale of Tempe.

The Greek government has declared three days of national mourning.
