Arab League foreign ministers agreed on Sunday to take all necessary measures to confront Islamic State and cooperate with international, regional and national efforts to combat militants who have overrun swathes of Iraq and Syria.
The Arab League also endorsed in the closing statement of its meeting in Cairo a UN Security Council resolution passed last month calling on member states to "act to suppress the flow of foreign fighters, financing and other support to Islamist extremist groups in Iraq and Syria".
Baghdad had earlier submitted a draft resolution endorsing its own efforts to confront militants who have seized large areas for a cross-border caliphate and to condemn Islamic State's actions as war crimes and crimes against humanity.
Diplomatic sources said before the meeting that Arab foreign ministers were set to endorse a U.S. aerial campaign against the group and Egypt's official Mena news agency said the ministers would agree to coordinate with the United States.
The final text did not directly endorse either the Iraqi or U.S. campaign against Islamic State, but diplomatic sources said the wording clearly offered Arab cooperation to U.S. and Iraqi efforts and could be read as a tacit agreement to back Washington's campaign against the group.
At the opening session, several foreign ministers spoke of the gravity of the challenge posed by Islamic State in Iraq as well as the violence that has engulfed Libya and other regions.
