The UN Security Council on Friday authorized countries to “take all necessary measures” to fight ISIS in a resolution that won unanimous backing a week after the Paris attacks.

The measure drafted by France calls on all UN member states to “redouble and coordinate their efforts to prevent and suppress terrorist attacks” committed by ISIS and other extremist groups linked to Al-Qaeda.

French President Francois Hollande welcomed the adoption, saying the resolution would “help mobilize nations to eliminate Daesh” [ISIS], which has claimed responsibility for the attacks that left 130 dead in Paris.

Foreign Minister Laurent Fabius said countries should now find concrete ways to shore up the fight, “either through military action, the search for political solutions or the battle against terrorist financing.”

The resolution does not provide any legal basis for military action and does not invoke chapter seven of the UN charter that authorizes the use of force.

But French diplomats maintain that it will provide important international political support to the anti-ISIS campaign that has been ramped up since the attacks in Paris a week ago.

“This resolution is a powerful international recognition of the threat posed by ISIL,” said British Ambassador Matthew Rycroft, who chairs the council this month.

The British envoy described it as a “call to action” to member-states to join in international efforts to defeat ISIS.

The measure calls on member states “that have the capacity to do so to take all necessary measures, in compliance with international law… on the territory under the control of ISIL, also known as Daesh, in Syria and Iraq.”
