Syria opposition activists are reporting intense government bombings of a number of neighborhoods that remain under rebel control in the city of Aleppo.
They say clashes are underway on Thursday along the fast-moving front line. The opposition Local Coordination Committees says government airstrikes and artillery hit at least six rebel-held neighborhoods in central and southeastern Aleppo
Opposition Thiqa news agency says the government dropped barrel bombs on al-Sukkari and Kallaseh neighborhoods.
Syrian troops and allied militiamen moved swiftly into rebel-held eastern Aleppo less than two weeks ago and are now in control of more than three quarters of the besieged rebel enclave.
Activists are struggling to document casualties because of street clashes and intense bombings.
The Syrian Civil Defense in Aleppo says it was able to record 38 killed in Wednesday's violence. The Syrian Observatory for Human Rights said 11 were killed in Aleppo's Old City, which was seized by the government Wednesday.
Meantime, the International Committee for the Red Cross says it has evacuated 148 disabled civilians and others in need of urgent care from a facility in Aleppo's Old City that is now under Syrian government control.
ICRC said in a statement on Thursday that the evacuation was possible after fighting calmed down in that part of the city. It said the evacuation was undertaken jointly with the Syrian Arab Red Crescent and was completed late on Wednesday.
The government secured the area after repelling rebels, who retreated to the south.
Pawel Krzysiek, ICRC communication coordinator in Damascus, says the evacuees had been "forgotten" amid the fighting.
He says they were trapped in a facility that was originally a home for the elderly. They include mental health patients, elderly orphans, and patients with physical disabilities. Some were injured civilians who had sought refuge there.
Krzysiek says they were evacuated to hospital and shelters in the western, government-held part of Aleppo.
