Germany: IS claim stabbing in Hamburg two weeks after attack *ARCHIVE*

The self-proclaimed Islamic State (IS; formerly ISIS/ISIL) claimed responsibility for a deadly knife attack which took place two weeks ago in Hamburg, with footage from October 16 showing the aftermath of the stabbing.
A young couple was sitting under a bridge at Alster River in central Hamburg when they were attacked by an unconfirmed assailant. The 16-year old male was stabbed several times from behind, and the 15-year old female kicked into the river by the assailant. The young man died of his injuries in hospital.
The attacker was allegedly responding to the militant organisation’s calls to target citizens of coalition countries. However, IS has claimed several random stabbings across Europe from the militant group's Amaq news agency, with officials casting doubt on the validity of the claims.
