German police kill Afghan teen after train axe attack

German police shot dead a 17-year-old Afghan refugee on Monday after he attacked train passengers with an axe and a knife, seriously wounding four in what one official said was a "probable" Islamist attack. Several other people were also injured in the assault on a regional train, police said, adding that the teenager was killed as he tried to flee. Joachim Herrmann, the interior minister of Bavaria state, said the assailant had arrived as an unaccompanied minor in Germany and had lived at first in a shelter and then more recently with a foster family. "It is quite probable that this was an Islamist attack," said a ministry spokesperson, adding that the assailant had shouted "Allahu akbar" (God is greatest). However he stressed that the investigation was ongoing and that the teenager appeared to have acted alone.
