Saudi Arabia called on Wednesday for an emergency UN Security Council meeting to discuss reports of a chemical attack that opposition groups say killed hundreds of people in Syria. "It is time for the Security Council to shoulder its responsibility and overcome differences between its members and restore the confidence of the international community by convening immediately to issue a clear and deterrent resolution that will put an end to this human crisis," Foreign Minister Prince Saud al-Faisal said in a statement. Leading Syrian opposition figure George Sabra said in Turkey the attack in which chemical weapons were used had killed 1,300 people.
