A teenage Afghan refugee armed with an axe and a knife injured four people on a train in Wuerzburg in Germany before being shot dead by police. Officials said, three people were seriously hurt while one suffered minor injuries.

The motive for the attack is not yet clear. Bavarian Interior Minister Joachim Herrmann said, the attacker was a 17-year-old Afghan refugee who had been living in the town of Ochsenfurt. He said, the teenager appeared to have travelled to Germany as an unaccompanied minor.
