Two shot dead in German airport

Two people have died after a gunman opened fire on a bus full of American soldiers at Frankfurt airport, police say.

The driver of the bus and a US soldier were reportedly killed, while two others were seriously injured.

A 21-year-old suspect from Kosovo is said to have been arrested after the shooting in front of Terminal 2 at Europe's second-biggest airport.

Police have told German media it is not clear if it was a terrorist attack.
