After four-and-a-half years and hundreds of thousands of deaths, Syrian President Bashar Assad's loyalists are ready to seize Aleppo, heralding the end of the rebellion era.
The government would soon gain full control over Aleppo as rebels are present only in a tiny corner of the city.
A deal brokered by Turkey and Russia would rescue trapped people and evacuate the last rebel-controlled region.

A US official said: "We remain skeptical. We've seen these kinds of declarations before by the Russians and the regime, and just as many times we've seen them violated and broken."

Russian officials said the deal would see rebel holdouts and civilians evacuated to other rebel-held areas near Aleppo or Idlib.

Assad government's biggest victory in the four-and-a-half-year-old war
The rebels' retreat would be Assad government's biggest victory in the four-and-a-half-year-old war.
Assad isn't in danger of being toppled as Russian airstrikes turned back rebel gains; the opposition might not be able to overthrow his regime.
However, the victory wouldn't end the Syrian civil war as rebels still control larger regions of Northwestern Syria, Southern Syria's countryside, territories around Damascus and near Homs.
Bloodshed could intensify, say diplomats
Diplomats now fear the bloodshed could intensify as the government, with Russia and Iran's support would fulfill Assad's promise to reclaim all rebel-controlled territories.
The government forces began retaking rebel areas since the last three years in Aleppo.
The complicated Syrian war has claimed over 400,000 lives.
Another factor contributing to bloodshed is that the Islamic State controls about one-third of Eastern Syria.
An US official's statement
"Two things are absolutely clear here. One, the regime (of Assad) doesn't have capability to end this war, even with Russia's backing, and the scorched-earth approach that they're taking is only going to attract more extremists."
