More than 50 civilians killed in Syria's Aleppo

At least 51 civilians, including four children, were killed in air raids and shelling attacks on Saturday in Syria's battleground city Aleppo and the neighbouring countryside.

Syrian air force raids left 15 people dead in rebel-held areas in the east of Aleppo city.

Nine civilians died in rebel shelling on the government-held west, the Syrian Observatory for Human Rights said.

Another 27 people were killed in Syrian and Russian raids targeting a string of towns in the west of Aleppo province, the Britain-based group added.

In a major push last week to end a siege on opposition-held eastern Aleppo, a coalition of rebels and Islamist fighters cut off the regime's own main access road on the southern edges of the city.

Each side has used their newly acquired territory to bring food and other supplies into neighbourhoods of the city they control, but the roads into rebel-held eastern Aleppo are still not safe for civilians to use.

The fighting in Aleppo is reported to have killed at least 130 civilians since the end of July, and has damaged hospitals, clinics, and the city's power and water networks.
