"An explosion hit near a restaurant, targeting the Americans, and there were some forces for the Manbij Military Council with them," one said. The US-backed, Kurdish-led Manbij Military Council militia that controls the town said there was preliminary information that people had been injured in Wednesday's attack.Manbij has been held by US-backed fighters allied to the Kurdish YPG militia since they took it from Islamic State in 2016. It is located near areas held by Russian-backed Syrian government forces and by anti-Assad fighters backed by Turkey.One of the witnesses said there was a "heavy" presence of military aircraft over Manbij following the blast, which took place near a vegetable market.Photographs on a local Kurdish news site, which Reuters could not verify, showed two mutilated bodies, several other bodies lying on the ground with people gathered around them, damage to a building and vehicles, and blood smears on a wall.
