Earlier on Monday two suicide bombers killed a number of people in the Syrian government-held city of Hama. The first blew himself up using an explosive belt in a square in the city’s al-Hader district, followed 15 minutes later by a second in the same location.

The almost entirely Kurdish-held city has often been targeted by jihadists of the Islamic State group. In July, over 25 civilians were killed in an ISIS suicide bombing attack in the city of Hasakah. Another attack, also in July, killed at least 50 civilians in the city of Qamishli.
