UN rights chief warns Aleppo 'slaughter' could happen elsewhere

U.N. human rights chief Zeid Ra'ad al Hussein called on Tuesday on the international community to demand Syria allow monitoring of its treatment of people fleeing eastern Aleppo, warning that populations of other opposition-held towns could face the same fate.

"The crushing of Aleppo, the immeasurably terrifying toll on its people, the bloodshed, the wanton slaughter of men, women and children, the destruction - and we are nowhere near the end of this cruel conflict," Zeid said in a statement.

"What is happening with Aleppo could repeat itself in Douma, in Raqqa, in Idlib. We cannot let this continue."
