Several people, including a cop, were injured after a knife-wielding person stabbed multiple people during an anti-Islamist political rally in Germany on Friday.

The attack was caught on camera during Youtube live stream.

The bloody mayhem erupted in the middle of a square in the city of Mannheim just after 11:30 a.m. local time as members of the right-wing campaign group, Citizens’ Movement Pax Europa (BPE), were filming a demonstration, reported New York Post.

Police reportedly shot the attacker but his condition is still not known.

The video showed paramedics trying to treat the injured people.
