Intense air raids shook Syria’s Aleppo on Tuesday as increasing tensions between Moscow and Washington poisoned efforts to revive a failed ceasefire. The UN Security Council was due to meet later for talks on salvaging the truce — which collapsed on Monday after only a week — but the mood was likely to be tense after the United States said it held Russia responsible for a deadly airstrike on an aid convoy.
US Secretary of State John Kerry and Russian Foreign Minister Sergei lavrov are both to address the council, ahead of more talks expected later this week. Russia and the United States co-sponsored the ceasefire plan, with Kerry warning it could be the “last chance” to try to end Syria’s civil war, which has killed more than 3,00,000 people in five years.
