Arab summit struggles to heal rifts

Warning of "enormous" dangers, Kuwait urged fellow Arab nations on Tuesday to resolve disputes complicating crises such as Syria's war and unrest in Egypt, but diplomats said tensions rose behind the scenes at their annual summit.

The gathering of the 22-member Arab League also heard an appeal from the UN-Arab League peace envoy, Lakhdar Brahimi, for an end to the flow of arms to combatants in the Syrian civil war, which has killed more than 140,000 people and displaced millions.

Brahimi did not name the suppliers, but Saudi Arabia and Qatar are believed to be the main Arab funders of military assistance to rebels in Syria, while non-Arab Iran is the main regional power backing President Bashar al-Assad.
