A well timed photographer, Burhan Ozbilici, was attending an art gallery where the Ambassador of Turkey was giving a speech. But suddenly shots barreled from the art museum and the Ambassador was killed.
Right after the shooting the photographer took shelter and snapped a few pictures of the shooter. The shooter was said to be screaming about Aleppo.
After guards were brought in, the shooter was killed and the photo's taken by the photographer indicated the man was standing behind the ambassador almost like a friend of a bodyguard.
