At least 21 people have been killed and dozens more injured following a collision between two high-speed trains in southern Spain on Sunday evening, officials say, BBC reported. 

The incident happened near the town of Adamuz, close to the city of Cordoba, when a high-speed train travelling from Malaga to Madrid derailed and crashed onto a neighbouring track, rail network operator Adif said.

A second train travelling in the opposite direction, from Madrid to Huelva, also derailed, according to BBC.
