Washington has urged for negotiations with Moscow over a deal that would envisage providing a safe passage to the US intelligence officers and terrorists in Eastern Aleppo to Turkey via the Castillo corridor in lieu of handing over the remaining districts to the Syrian army, media reports said Tuesday.

The Arabic-language al-Hadas news website quoted unnamed informed sources as saying on Tuesday that the negotiations are meant to help US spies, including an intelligence officer involved in battle arrangement for the terrorists and an informant named Balal Abdel Karim, leave the Aleppo city.

Earlier on Tuesday, media sources disclosed that a large number of militants have been negotiating secretly with government officials in Aleppo to surrender themselves and leave the city.

The Arabic language al-Watan newspaper reported that continued defeats of Jeish al-Fatah and devastating advances of the Syrian army troops in the Eastern districts of Aleppo city have widen rifts amongst militant groups.

The paper added that a large number of militants have had secret negotiations with government officials to pave the ground for their amnesty and their evacuation to the Western districts of Aleppo that are under army’s control.

Meanwhile, Israel Shamir, an expert in Middle Eastern affairs, told Radio Sputnik that reports from newspapers loyal to militants occupying Eastern Aleppo indicate they are preparing to surrender to government forces

“Right now in Aleppo there is a kind of situation in which is very hard to try and predict anything. But there is a feeling that those fighting in East Aleppo have begun to understand that they won’t succeed. Over the last two days reports have begun to appear in media outlets which support the rebels, saying ‘this is not the end, we are losing Aleppo but it’s not that bad, we will fight in other places.’ They are kind of consoling messages. This is, in principle, a sign that they are ready to surrender Aleppo,” Shamir said

The analyst warned that although the liberation of Aleppo would represent a major breakthrough, militants who have left Aleppo might reappear in other areas of conflict.

On Monday, Syrian military helicopters dropped thousands of leaflets over the terrorist-held districts of Aleppo city, urging militants to give up fight and surrender themselves to the authorities.

Helicopters of the Syrian Army dropped thousands of leaflets over the Eastern neighborhoods of Aleppo city, calling on militants to lay down their arms, ask for amnesty and allow the civilians to leave the war-hit neighborhoods.
