The Canadian national and freelance photographer was killed in the Syrian city of Aleppo by a barrel bomb, according to the French Press Agency, AFP.

Reports said that the photographer, who reportedly supplied pictures to SIPA and EPA agencies, was taking photographs of the damage caused by an earlier bomb launched from helicopters of the Syrian army at a roundabout in Haydariyeh when an unexploded barrel bomb went off, killing him.

Mustafa had worked in Syria periodically since early 2013, as well as in Israel and the Palestinian territories, Egypt and Brazil.
