BEIRUT - The U.N. human rights office says it has received reports of Syria's pro-government forces killing at least 82 civilians as they entered the last remaining strongholds of the rebels in eastern Aleppo.

Spokesman Rupert Colville of the U.N. human rights office says the reports recount pro-government forces entering homes and killing some civilians "on the spot" in the former rebel enclave.

He says 11 women and 13 children were among those reportedly killed in four neighborhoods of the increasingly-shrinking rebel enclave in the city of Aleppo.

Colville says the reports came in late the previous evening and that he doesn't know exactly when the killings took place.
