A Kurdish news agency and a Syrian war monitoring group say a missile attack by the Islamic State group in eastern Syria has killed at least one Kurdish fighter and wounded two British soldiers embedded with them.

The Rudaw news agency says the two British soldiers are in a stable condition.

British special forces are known to be on the ground in northern Syria although the British government does not provide details about their presence.

The Britain-based Syrian Observatory for Human Rights said in a report Sunday that the IS attack occurred the previous day in the village of Shaafa in eastern Deir el-Zour province amid fierce clashes between the Kurdish-led Syrian Democratic Forces, backed by the U.S.-led coalition, and IS militants.
