Aleppo battle: UN says 82 civilians shot on the spot
The UN's human rights office said it had reliable evidence that in four areas 82 civilians were shot on sight.
"We're filled with the deepest foreboding for those who remain in this last hellish corner" of eastern Aleppo, said spokesman Rupert Colville.
Rebels, who have held east Aleppo for four years, are on the brink of defeat.
Thousands of people are reportedly trapped in the last remaining neighbourhoods still in rebel hands, facing intense bombardment as pro-government troops advance.
Both the UN and the International Committee of the Red Cross (ICRC) have appealed to Syria and its ally Russia to end the bombardment and allow civilians a safe passage out.
'Numerous bodies on streets'
At a news conference in Geneva, Mr Colville gave details of atrocities his office had received reports of, admitting it was impossible to verify their accuracy.
He said that of the 82 civilians reportedly shot, 11 were women and 13 were children.
"Yesterday evening, we received further deeply disturbing reports that numerous bodies were lying on the streets," Mr Colville added.
"The residents were unable to retrieve them due to the intense bombardment and their fear of being shot on sight."
Jens Laerke, a UN humanitarian spokesman, said that it looked like a "complete meltdown of humanity in Aleppo".
