The Syrian army said it had taken a strategic district of Aleppo on Tuesday in what would mark the most important advance in the divided city by Damascus and its allies in weeks, but rebels said the battle was not over.

The 1070 Apartments district is located on the southwestern outskirts of Aleppo and lies alongside the government's corridor into the parts of the city that it controls.

The Syrian Observatory for Human Rights, a U.K.-based group that reports on the war, said government forces and their allies had seized full control of 1070 Apartments, calling it the most significant gain by the government in Aleppo since September.
