A man drove a van into a crowd in the western German city of Muenster, killing two people before shooting himself dead.

Police in Germany say they do not know why a man drove a van into a crowd in the city of Muenster which killed two people.

There has been a heightened sense of security in Europe, after similar vehicle attacks in the UK, France and Sweden.

German officials say complete security is not possible with lone wolf attacks.
