BEIRUT (Reuters) - Syrian government forces and rebels fought battles in the centre of Aleppo and north of the city on Friday, a week into a Russian-backed offensive by the Syrian army to take the entire area, a war monitor and sources on both sides said.
There were conflicting accounts on the outcome of Friday's fighting. The Syrian Observatory for Human Rights and a Syrian military source said government forces had captured territory north of Aleppo and buildings in the city centre.
An aerial bombardment of rebel-held areas continued on Friday, with heavy air strikes in the Shaar district where incendiary material struck a complex of medical buildings, the complex's director and other medical workers said.
Syrian state television reported that a child had been killed and others injured by rebel shelling in the government-held al-Ithaa neighbourhood of Aleppo.
Rebel sources however denied there had been any additional advances north of the city by government forces that seized the Handarat camp area north of Aleppo on Thursday. A rebel official said government forces had advanced in the Suleiman al-Halabi district of central Aleppo, but were then forced to withdraw.
The Syrian military and its allies launched a Russian-backed offensive one week ago aimed at capturing rebel-held districts of eastern Aleppo that are home to more than 250,000 people.
Aleppo, Syria's largest city and commercial hub before civil war began in 2011, has been divided into government and opposition sectors for four years.
A water station was bombed in Suleiman al-Halabi, on the front line to the north of Aleppo's Old City, dealing a further blow to a water system already badly damaged during the offensive.
The Observatory blamed government forces. A Syrian military source, however, said rebels had blown it up and state media later said that insurgent shelling of Suleiman al-Halabi and the adjacent government-held al-Midan district had killed 15 people.
The Islamist Jabhat Fateh al-Sham group, formally known as the Nusra Front until it broke its formal allegiance to al Qaeda in July, said that eight of its fighters had been killed fighting at Suleiman al-Halabi.
The Observatory, a British-based war monitor, reported heavy bombardment by government forces and "back and forth" fighting in the Suleiman al-Halabi neighbourhood.
The Syrian military source said government forces captured several buildings in the area and were "continuing to chase the remnants of the terrorists fleeing them".
The rebel official however said government forces had "advanced and then retreated", losing "a number of dead". Zakaria al-Malahifji, an official for the Fastaqim rebel group that is present in Aleppo, said the insurgents still controlled the water plant.
In the fighting north of Aleppo, the Observatory and a television station operated by Hezbollah said government forces had taken the Kindi Hospital area adjacent to the Handarat Palestinian refugee camp, a few kilometres (miles) from the city. Hezbollah is a Lebanese group fighting alongside the army.
But rebel sources denied that the government had captured the Kindi Hospital area, saying fighting was still going on.
A senior rebel official also said that government forces were shelling the rebel-held districts with artillery from a hilltop to the east of Aleppo.
