MISSILES used in an Isis attack in which two British soldiers were seriously injured in Syria yesterday may have been sold to the jihadists after being supplied by the United States to opposition groups.

The pair were hit in a missile attack launched on a Syrian Democratic Forces (SDF) base in Deir Ezzor, northern Syria. A fighter from the largely Kurdish People’s Protection Units (YPG) was killed in the blast.

The role of British soldiers in Syria remains a secret, with the Ministry of Defence refusing to comment on the operations of special forces. It is believed that they are fighting alongside the SDF.
