The United States threatened on Wednesday to halt its diplomacy with Russia on Syria and it said it held Russia accountable for the use of incendiary and bunker-busting bombs on Aleppo - a view a U.S. official said could open Moscow up to charges of war crimes. Secretary of State John Kerry conveyed the message in a call to Russian Foreign Minister Sergei Lavrov in which he voiced "grave concern" over the Russian-backed Syrian government's air and land assault on rebel areas of Aleppo, Syria's largest city.
By John Irish and Michelle Nichols PARIS/UNITED NATIONS (Reuters) - France's foreign minister said on Wednesday he was working to put forward a U.N. Security Council resolution for a ceasefire in the Syrian city of Aleppo, and that any country that opposed it would be deemed complicit in war crimes. Speaking to lawmakers, Jean-Marc Ayrault accused Syria, backed by Russia and Iran, of carrying out an "all-out war" on its people, something that Paris could not sit by idly watching.
Russian Foreign Minister Sergei Lavrov urged U.S. Secretary of State John Kerry on Wednesday to make good on U.S. pledges to separate Washington-oriented units of Syrian opposition from "terrorist groups", Russia's Foreign Ministry said on Wednesday. Lavrov told Kerry in a telephone conversation that warlords from the Nusra Front had openly spoken about foreign support, including supplies of U.S. weapons.
