DAMASCUS, Nov 27 (Al Jazeera): The Syrian army said it had taken control of an important district in rebel-held eastern Aleppo on Saturday after fierce fighting, with rebels blaming intense air strikes and lack of hospitals for their collapsing frontline.
Government forces advanced with a ground and air assault on the edge of the besieged eastern half of the city into the Hanano housing area, a move designed to split the rebel-held east in two.
Syria's war: 'There's no food in Aleppo's shops or markets'
Aleppo, which was Syria's biggest city before the start of a civil war that has killed hundreds of thousands of people, is divided between the government-held west and rebel-held east, where UN officials say at least 250,000 people are under siege.
Capturing all of Aleppo would be a major victory for Syrian President Bashar al-Assad after five and a half years of fighting.
The army said in a statement it had, alongside its allies, taken full control over the Hanano housing district, which is on the northeast frontline of the eastern sector.
"Engineering teams are removing mines and improvised explosive devices planted by terrorists in the squares and streets," the statement said.
The Syrian government calls all forces fighting against it "terrorists".
An official in an Aleppo rebel group said a map circulated by pro-government media showing government forces in control of the Hanano area was largely accurate.
The UK-based Syrian Observatory for Human Rights said the army had established control over Hanano, which was the first part of Aleppo taken over by armed opposition groups in 2012.
A renewed air assault on residential and frontline parts of east Aleppo began last Tuesday after a weeks-long pause in air strikes and shelling there.
"Every day there are a lot of attacks, helicopters dropping barrelbombs and war planes dropping bunker-buster bombs and cluster munitions," Modar Shekho, an emergency nurse in al-Shaar neighbourhood, told Al Jazeera.
An official from Jabha Shamiya, one of the biggest groups fighting against Assad in northern Syria, told Reuters news agency: "The revolutionaries are fighting fiercely but the volume of bombardments and the intensity of the battles, the dead and the wounded, and the lack of hospitals, are all playing a role in the collapse of these frontlines."
Members of Jabha Shamiya have taken part in the fighting in Hanano.
He condemned the "international silence" and said the government and its allies were trying to exploit the period before the next US administration took over.
"The Iranians, Russians and regime know there is a vacuum and they are trying to exploit it using all means," he said.
"We are in touch with the friendly states but unfortunately Aleppo is being left to be slaughtered."
Yasser al-Yousef, from the political office of the Nour al-Din al-Zinki rebel group, said rebel fighters had fought fiercely for more than 48 hours to defend Hanano and the southern front of east Aleppo from heavy government bombardment.
A Syrian state television reporter broadcast live from a part of Hanano on Saturday as government forces sought to establish full control over the area. Gunshots could be heard and behind him damaged buildings and rising smoke could be seen.
