Syrian regime forces advanced in the battleground city of Aleppo Friday, backed by a Russian air campaign that a monitor said has killed more than 3,800 civilians in the past year.
The Doctors Without Borders (MSF) charity accused Syria's government and its ally Moscow of provoking a "bloodbath" in the city, saying the eastern rebel-held portion had become "a giant kill box".
Syria's army was advancing on two Aleppo fronts, as talks between key players Washington and Moscow -- which back opposing sides in the war -- appeared on the verge of collapse.
Damascus's bid to recapture all of the divided northern city prompted the UN to warn of "a humanitarian catastrophe".
Just over a week after it announced an operation to recapture all of Aleppo, the army was advancing both in northern and central Aleppo, according to the Syrian Observatory for Human Rights monitor and state media.
In the north, it recaptured the Handarat former Palestinian refugee camp, as well as the old Kindi hospital, said Observatory director Rami Abdel Rahman.
Rebels had held the hospital since 2013, and capturing it allows government forces to threaten the opposition-held Heluk and Haydariyeh neighbourhoods in northeast Aleppo.
"The regime's strategy is to chip away until it reaches the heart of the rebel-held areas," Abdel Rahman said.
In central Aleppo, meanwhile, fierce clashes shook the Suleiman al-Halabi neighbourhood, which is divided by the frontline separating the rebel-held east and regime-held west.
The army is seeking to capture the opposition-held sector of the district and advance to the main water supply station for the government-controlled part of Aleppo which is in the neighbourhood.
State television said 15 civilians had been killed and 40 wounded by rocket fire into the government-held part of Suleiman al-Halabi and neighbouring Midan district.
The Observatory and an AFP correspondent on the ground said air strikes on Friday were focused on the battlefield, unlike in previous days which saw heavy bombardment of civilian areas.
Since the army operation began, Damascus and Moscow have pounded east Aleppo with air strikes, barrel bomb attacks and artillery fire, killing 216 people, including more than 40 children, according to the Observatory.
The assault has levelled apartment blocks and put hospitals out of service, creating a humanitarian catastrophe in opposition areas that have been under siege for most of the past two months.
It has been some of the worst violence since the March 2011 beginning of the conflict, which has killed more than 300,000 people and displaced over half the population.
Outside Damascus, meanwhile, air raids on several rebel-held towns in the Eastern Ghouta region killed at least 17 people including eight children, the Observatory said.
