Air strikes on rebel-held areas of Syria reportedly killed at least 82 people hours after the US and Russia announced plans for a truce. Opposition activists said an air strike on a market in Idlib killed at least 37 people while at least 45 died in strikes on Aleppo province. A 10-day truce is meant to start on Monday, followed by co-ordinated air strikes against terrorists. Turkey and E.U. welcomed the plan but warned that further action was needed.
