UN voices fear that hundreds missing after fleeing east Aleppo

The U.N. human rights office voiced concern Friday that hundreds of men may have gone missing after fleeing eastern Aleppo into government-controlled parts of the city.

"While it's very difficult to establish the facts in such a fluid and dangerous situation, we have received very worrying allegations that hundreds of men have gone missing after crossing into government-controlled areas," rights office spokesman Rupert Colville told reporters in Geneva.
