Residents of rebel-held parts of Aleppo say a Russian-backed air campaign against their city is targeting schools, marketplaces and hospitals. <br /> <br />Footage obtained by Reuters, and filmed on Wednesday (September 28), showed burning buildings and a scene of devastation in several neighbourhoods of the city. <br /> <br />The Syrian Civil Defence said they lacked enough resources to be able to deal with so many fires and emergencies. <br /> <br />Syrian government forces and rebels fought battles in the centre of Aleppo and north of the city on Friday (September 30), a week into the Russian-backed offensive by the Syrian army to take the entire area, a war monitor and sources on both sides said. <br /> <br />There were conflicting accounts on the outcome of Friday's fighting. <br /> <br />The Syrian Observatory for Human Rights and a Syrian military source said government forces had captured territory north of the city and buildings in the city centre. <br /> <br />Rebel sources however denied any additional advances north of the city by government forces that seized the Handarat camp area north of Aleppo on Thursday. <br /> <br />The Syrian military and its allies launched an offensive one week ago aimed at capturing rebel-held districts of eastern Aleppo that are home to more than 250,000 people.
