Fighting continues in Aleppo, Syria, as rebels fend off government forces.

Unverified amateur video from a social media website purports to show a battle between rebels, who are seen here, and the Syrian army.

Later, rebels are shown celebrating what they say is the taking of another district in Aleppo.

More amateur video-- this time from eastern city of Albu Kamal. The video purports to show the aftermath of an attack by Syrian forces.

The Syrian Observatory for Human Rights says more than 23,000 people have died in the uprising that began nearly a year and a half ago.
