The US and Russia have announced that they will resume talks on Syria, which broke down earlier this month.
Washington broke off all negotiations with Moscow nine days ago amid extreme tension over failure to secure a truce.
But Russia’s Foreign Minister Sergei Lavrov will now meet his US counterpart John Kerry and other key regional powers in Switzerland on Saturday.
The announcement comes after two days of renewed air strikes on Aleppo, killing at least 75 people.The US State Department said Mr Kerry would discuss a “multilateral approach” to ending the crisis,
“including a sustained cessation of violence and the resumption of humanitarian aid deliveries.”
The key regional powers, Saudi Arabia, Turkey and Iran are also expected to attend the talks in Lausanne.
Mr Kerry will follow his talks in Switzerland with a trip to London on Sunday.
The UN has appealed for a halt to the violence to allow aid into the besieged territory.
