Mustafa, a Canadian freelance photographer, was killed along with seven other individuals in consecutive bomb blasts in Aleppo. Mustafa was reporting on the first blast, which was caused by a barrel bomb dropped by a regime helicopter, when a second bomb exploded, according to news reports.
Mustafa, an activist and photographer, had documented Arab protest movements in Egypt and the Occupied Palestinian Territory. He had recently started working for the Germany-based European Pressphoto Agency and the Paris-based photo agency SIPA, according to The Associated Press. His images for EPA had been picked up by multiple outlets, including The Guardian, The Times of London, and Radio Free Europe/Radio Liberty.
A vigil in Mustafa's honor was held in his hometown of Toronto on March 9, the Canadian press reported.
