Syrian rebels gather at a hideout in Aleppo, planning an attack on government forces.

Aleppo has suffered fierce fighting as the government tries to regain control of the city.

Rebels have been battling to hold their ground, while facing troops backed by warplanes and tanks.

Along with the capital Damascus, Aleppo is seen as vital for the ruling regime as it continues to cling to power.
