ISIS’s Amaq news agency announced it was responsible for a killing perpetrated on October 16 on a 16-year old youth near Alster bridge in Hamburg: “A soldier of the Islamic State stabbed two individuals in Hamburg city on the 16th of this month. He carried out the operation in response to calls to target the citizens of coalition countries.”
The perpetrator attacked a 16-year-old youth repeatedly from behind and kicked his 15-year-old female companion into the river. The stabbing victim died of his injuries in the hospital while the young woman managed to escape.
A police spokeswoman in Hamburg declined to comment on ISIS's claim.
