"The jihadi group surging through Iraq and Syria is using large captured US-made weapons and has access to anti-tank rockets supplied by Saudi Arabia to a moderate rebel group, according to a report published on Monday.
The study by the London-based Conflict Armament Research consultancy found that Islamic State (Isis) militants had access to large numbers of US weapons, which they were shifting to key battlefields.
The report drew no conclusions about how the weapons were sourced. However, the capitulation of the Iraqi army in northern Iraq on 10 June gave the jihadis access to military arsenals in the north of the country, which were full of US-supplied assault rifles and ammunition, as well as heavy weapons."
