The Latest: US, France, UK walk out of UN when Syria speaks
The ambassadors of the United States, Britain and France walked out of the U.N. Security Council when Syria's ambassador was called to speak at an emergency meeting they called for in order to demand a halt to the Syrian offensive in Aleppo.
The walkout on Sunday by U.S. envoy Samantha Power, Britain's Matthew Rycroft and France's Francois Delattre demonstrated Western anger and frustration at Syrian President Bashar Assad's decision to try to take Aleppo after U.S.-Russian talks failed to revive a cease-fire.
The International Committee for the Red Cross says it has delivered food, medical supplies, and other supplies to a set of four besieged Syrian towns that have been inaccessible to aid organizations in nearly six months.
The Syrian Arab Red Crescent, which is managing the convoys jointly with the U.N. and the ICRC, says 53 trucks have reached Madaya and Zabadani, besieged by pro-government forces, and 18 trucks have reached Kafraya and Foua, which are besieged by rebels.
The Britain-based Syrian Observatory for Human Rights says at least 23 people have been killed in presumed government or Russian airstrikes on various neighborhoods in rebel-held eastern Aleppo on Sunday.
Ibrahim Alhaj of the Syrian Civil Defense search and rescue operation says the group has documented the deaths of 43 people so far.
Staffan de Mistura said Syria's declaration of a military offensive to retake rebel-held eastern Aleppo has led to one of the worst weeks of the 5 1/2-year war with dozens of airstrikes against residential areas and buildings causing scores of civilian deaths.
De Mistura said U.S.-Russian talks on the sidelines of the U.N. General Assembly's ministerial meeting failed to reinvigorate the Sept. 9 cessation of hostilities, and the offensive has left two million people in Aleppo without water.
The foreign minister of Great Britain Boris Johnson said in a broadcast of the BBC that Russia is guilty of protracting civil war in Syria and, possibly, of committing war crimes in the form of air attacks on convoys with humanitarian aid.
France's foreign minister says Russia and Iran will be guilty of war crimes if they don't pressure Syrian President Bashar Assad to stop escalating violence.
The Britain-based Syrian Observatory for Human Rights, which maintains a network of local contacts, says rebels seized Handarat, a largely uninhabited Palestinian refugee camp, early Sunday.
