BREAKING: Syrian asylum-seeker kills woman, injures 2 with machete at German bus station

Police say a Syrian asylum-seeker killed a woman with a machete and wounded two others outside a bus station in the southwestern German city of Reutlingen before being arrested.

Police spokesman Bjoern Reusch said in a statement Sunday that witnesses said the 21-year-old man, who was known to police, was having an argument with the woman before attacking her about 4:30 p.m. Police say the motive behind the attack is still not clear.

The attack comes as Germany is on edge following a rampage at a Munich mall on Friday night in which nine people were killed, and an ax attack on a train a week ago that left five wounded in southern Germany.
