Amman: Islamic State said one of its suicide bombers killed some people on Monday at a military base in Syria's Raqqa city, which is under control of a U.S.- backed and Kurdish-led militia.
The Syrian Democratic Forces (SDF), led by Kurds, said a militant blew himself up in a blast that killed one civilian and injured several of its fighters.
Though the SDF did not say where the blast took place, two Raqqa residents reached by Reuters said they heard an explosion in a central district of the city housing military
offices.
Islamic State's (IS) claim of responsibility came in a statement by the affiliated Amaq news agency.
It said the attack targeted a recruitment centre in Raqqa and that 17 people were killed or wounded.
Amaq said the bomber, whom it named as Abu Abdullah al Shami, had first used his machine gun then detonated a vest.
The SDF also said earlier it had clashed with IS fighters who infiltrated through an old tunnel in the city near an outpost where their fighters were stationed.
