Under fire in Aleppo

Rebels on the frontlines in Aleppo.

Amateur video out of Syria which could not be independently verified by Reuters appears to show rebels holding positions in the Salaheddine district of Aleppo.

Both the Syrian government and rebels have claimed to have control of Salaheddine, a gateway into the city of 2.5 million people and the main focus of fighting in the past week.

Reuters journalists have witnessed fierce street fighting in the district, with Syrian government tanks pounding alleyways where rebels took shelter.

Syrian army tanks shelled Aleppo Sunday and a helicopter gunship hit rebel positions with heavy machinegun fire.

With a U.N. backed ceasefire a distant memory, rebels have been battered by the government onslaught in Aleppo and the capital Damascus.

On Sunday State television aired footage of men they say are captured rebels.

Activists say some 18,000 people have been killed in Syria since the uprising began last March.
