Russia and the Syrian government denied Tuesday they were behind the airstrikes on a humanitarian aid convoy in northern Syria that killed at least 12 people and cast further doubt on the fate of a cease-fire aimed at bringing a semblance of calm to the war-torn country.

No airstrikes on the United Nations humanitarian convoy in the southwestern outskirts of Aleppo were carried out by Russian or Syrian aviation, the Russian military said in Moscow.
