Four killed, 13 seriously injured in bus crash

Four people have been killed after a double-decker bus crashed into a metal roof at a passport checkpoint in Denmark.

Sixteen others were injured, 13 seriously.

The bus accidentally drove down a lane for cars as it passed through the passport control checkpoint in the port city of Gedser.

The bus, which was carrying Bosnians who live in Sweden, was about a metre higher than the metal roof, said police spokesman Karsten Overvad.

The bus had disembarked from a ferry from Rostock, a northern Germany port town, and was on its way back to Sweden.
