A 17-year-old Afghan refugee was shot dead by police after injuring four passengers in a slashing attack aboard a train late Monday near Wuerzburg in the southern German state of Bavaria, authorities said. 
Three people were seriously hurt and one suffered minor injuries in the attack, police said. Another 14 were treated for shock. 
An initial investigation found that the attacker, who wielded a knife and an axe, came to Germany as an unaccompanied minor, Bavarian Interior Minister Joachim Herrmann told German broadcasters (dpa). 
After the attack, the boy tried to flee. A police special operations unit, which happened to be nearby at the time of the incident, pursued the suspect, who was shot dead when he tried to attack the officers.
