Syrian military video shows army advancing into Aleppo rebel district

Pro-government forces tightened their grip around the besieged Syrian city of Aleppo on Thursday (July 28) where the local governor said safe corridors had been opened for civilians to escape rebel-held areas.

A quarter of a million civilians still live in Aleppo's opposition-controlled eastern neighbourhoods, effectively under siege since the army and allied militia cut off the last road into rebel districts in early July.

State television quoted the governor of Aleppo as saying three humanitarian corridors would be established and President Bashar al-Assad offered an amnesty for rebels who surrender within three months.

His ally, Russia, said a fourth corridor would be set up in the north of the city for surrendering rebels, near the Castello road which the army recently seized.

The UK-based Syrian Observatory for Human Rights, said helicopters over rebel-held areas dropped baby diapers and meal packs that had Russian language labels.

Russian Defence Minister Sergei Shoigu said: "On behalf of the President of the Russian Federation, today, (we will) start a large-scale humanitarian operation together with the Syrian government to help civilians in Aleppo."

Aleppo, Syria's biggest city before the outbreak of the conflict five years ago, has been divided between government forces and rebels since the summer of 2012. Its recapture would mark Assad's biggest victory so far in the civil war.

The army, backed by allied militia forces and air support from Syrian and Russian jets, has taken more ground on the northern edge of the city, around the Castello road which leads out towards Turkey.

State television said the army had advanced in the Bani Zeid district, on the southern side of the Castello road. The Syrian Observatory for Human Rights said the pro-government forces had taken full control of the district.

A rebel source confirmed that the army had made advances. He said Kurdish forces from the nearby Sheikh Maqsoud district had also taken advantage of the fighting to advance into a housing complex in Bani Zeid.

"There has been a (rebel) withdrawal, but no one has surrendered," Zakaria Malahifji of the Aleppo-based rebel group Fastaqim group told Reuters.
