Almost 2,000 people have been killed by Syrian government air attacks in the northern city of Aleppo so far this year, an activist group says.

The dead included 283 women and 567 children, according to the Syrian Observatory for Human Rights (SOHR).

The Syrian air force has used so-called "barrel bombs" dropped from aircraft to try to put down a rebellion against President Bashar al-Assad.

Aleppo has seen fierce fighting since a rebel offensive in the area in 2012.

The UK-based SOHR said 1,963 people had been killed in the city - Syria's largest - and the surrounding area since January.

The government has used air and ground forces to drive the rebels back, but they remain in control of some areas to the east of Aleppo.

The SOHR - which has a network of activists around the country reporting on the violence - says more than 162,000 people have been killed in the three-year conflict.
