Syrian residents, fleeing violence in the restive Bustan al-Qasr neighborhood, arrive in Aleppo's Fardos neighborhood after regime troops retook the area from rebel fighters, on Dec. 13, 2016.
Russia and Syrian rebel groups said on Tuesday that a deal has been reached to evacuate fighters from a besieged pocket of the city of Aleppo, an agreement that would conclude a more than four-year battle for one of Syria's most important cities.
If implemented, the last-minute agreement would mark a turning point in more than five years of revolt and civil war in Syria, dealing a defeat to the opposition in a central battlefield of the conflict. The arrangement could save the lives of rebel fighters who have defended a portion of the city since 2012.
The fate of civilians trapped in the besieged rebel sector remains unclear. Rebel groups say the agreement will also permit civilians to exit the city. But speaking at the United Nations on Tuesday, Russian envoy Vitaly Churkin said, "The agreement is for the fighters to leave. The civilians, they can stay, they can go to safe places, they can take advantage of the humanitarian arrangements that are on the ground," according to Reuters.
If it does not apply to civilian activists and ordinary residents, the deal could raise concerns. According to the U.N. hundreds of men have gone missing after fleeing to government-held parts of Aleppo, triggering fears that they had been detained or forcibly disappeared by the regime.
The announcement of an agreement followed reports of extreme violence on the ground in Aleppo. Earlier on Tuesday, the U.N. Office for the High Commissioner for Human Rights said in a statement on Tuesday that at least 82 civilians had reportedly been killed by forces supporting the regime of President Bashar Assad in four neighborhoods in the besieged section of Aleppo.
As the regime and its allies advanced in recent days, civilians fled for their lives. Some of them have been forced to turn to government-controlled areas, others to what remains of the rebel sector, where an estimated tens of thousands of civilians remain, many of them believing that they are simply waiting for death.
The reported killings came as pro-government forces, including militias from Iraq, squeezed the besieged rebel-held pocket of the city. "There were no results. Russia refuses everything. The regime refuses everything," said Col. Abdul Jabbar Akaidi of the Free Syrian Army, a loose alliance of opposition groups. "They want to kill everyone," he added in a phone interview.
The current crisis is a crescendo of more than four years of armed struggle over Aleppo since rebels seized part of the city in 2012. The Assad regime and allied militias have encroached on rebel territory since late September 2015 when Russia unleashed an intense campaign of airstrikes that devastated the opposition held section of the city.
On Nov. 28, pro-Assad forces staged a lightning advance, and recaptured all but a handful of surrounded neighborhoods. According to the U.N., an estimated 37,000 people fled into government-controlled areas during the most recent offensive.
