UN Approves Resolution Urging Action Against Islamic State
The U.N. Security Council unanimously approved a French-sponsored resolution Friday calling on all nations to redouble and coordinate action to prevent further attacks by Islamic State terrorists and other extremist groups. The resolution says the Islamic State group "constitutes a global and unprecedented threat to international peace and security" and expresses the council's determination "to combat by all means this unprecedented threat."
The measure is the 14th terrorism-related resolution adopted by the U.N.'s most powerful body since 1999. It was adopted a week after violent extremists launched a coordinated gun and bomb assault that killed 130 people in Paris which the Islamic State claims it carried out. It also comes eight days after twin suicide bombings in Beirut killed 43 people, and three weeks after a Russian airliner crashed over Egypt's Sinai peninsula killing all 224 people on board — both attacks also claimed by IS.
The resolution "unequivocally condemns in the strongest terms" these and earlier "horrifying terrorist attacks" carried out by the Islamic State this year in Sousse, Tunisia and Ankara, Turkey. The resolution calls on U.N. member states "that have the capacity to do so to take all necessary measures" against the Islamic State group and all other violent extremist groups "to eradicate the safe haven they have established over significant parts of Iraq and Syria."
This does not constitute an authorization for military action, however, because the resolution is not drafted under Chapter 7 of the U.N. Charter which is the only way the United Nations can give a green light to the use of force...............
Britain poised for Syria air strikes after Labour revolt against Jeremy Corbyn
Up to 60 Labour MPs could back military intervention in Syria in defiance of Jeremy Corbyn on the basis of a UN resolution calling for "combat by all means" to be used to wipe out Isil
Britain is poised to join air strikes against Isil in Syria after senior Labour MPs publicly defied Jeremy Corbyn and pledged cross-party support for international action in the wake of the Paris terrorist attacks.
Hilary Benn, the shadow foreign secretary, welcomed a UN security council resolution - poised to be passed tonight- calling for "combat by all means" to be used to wipe out Isil.
Labour insiders said that the resolution is likely to be enough to convince as many as 60 Labour MPs of the need to extend RAF air strikes to Syria - something which would boost David Cameron's chances of passing a vote in the Commons. Shadow cabinet ministers say that military intervention is even more likely after the party's own legal advice suggested that there is a "sound basis" for air strikes even without the UN approval..........
