BEIRUT – Syrian opposition member Hadi al-Bahra is urging countries to threaten and if necessary take military action to deter all violations of the cease-fire demanded by the U.N. Security Council throughout Syria — not only for using chemical weapons.
He told an informal meeting of the Security Council on Monday: “It is feasible. It is necessary. And it is overdue.”
Al-Bahra is a member of the Syrian Negotiation Commission. He spoke to the council after U.S. Ambassador Nikki Haley warned that the United States is prepared to take military action again for chemical attacks that are killing and injuring Syrian civilians.
Al-Bahra said that if Syrian ally Russia blocks the Security Council from taking measures under Chapter 7 of the U.N. Charter, action should be taken outside the council to enforce its resolutions.
