Islamic State fighters hit US-aided Syrian force
The main U.S.-backed Syrian faction fighting the Islamic State group says members of the extremist group have attacked one of its positions, killing a civilian and wounding several other fighters in the northern city of Raqqa.
The Syrian Democratic Forces said in a statement that during Monday's attack, an IS fighter blew himself up near an SDF checkpoint.
The Britain-based Syrian Observatory for Human Rights, a war monitor, said the suicide attacker first opened fire at an SDF force outside a local department before going inside and blowing himself up killing five, including four civilians, and wounding eight.
SDF fighters captured Raqqa, once the de facto capital of the extremists, in October 2017.
Since then IS sleeper cells have carried out attacks in the city.
