The UN’s human rights office says hundreds of men and boys appear to have gone missing after leaving rebel-held areas of Aleppo. Forces led by Syria’s government have seized at least 75% of eastern parts of the city from rebels in recent weeks. Tens of thousands of civilians have fled those districts, with more than 8,000 leaving during a humanitarian pause on Thursday. The UN said evidence of disappearances has now started to emerge. Earlier, Russia said that Syria’s army has suspended combat operations in eastern Aleppo to allow for the evacuation of civilians trapped in the battle zone. Speaking on the sidelines of a European Foreign Ministers meeting in Hamburg, Russian Foreign Minister Sergei Lavrov said combat operations by the Syrian army have been halted in eastern Aleppo because there is a large operation under way to evacuate civilians. He said some 8,000 people would be taken out. Lavrov further said Russian and us military experts would meet in Geneva on Saturday to discuss ways of bringing an end to the violence in Aleppo.
