Remaining Syrian Rebel-held Aleppo Districts Possibly Hours from Falling by Jamie Dettmer The fall of rebel-controlled districts of eastern Aleppo to the forces of President Bashar al-Assad is likely to prove a decisive victory in the five-year civil war. The fall has major symbolic significance and leaves the regime and its foreign backers, Russia and Iran, free to focus their military might on remaining rebel strongholds in the rest of western Syria. While rebel commanders and opposition politicians insist the loss of Aleppo won't mark the end of the uprising, few doubt battlefield fortunes have swung heavily against them and with the regime possibly hours away from seizing what is left of insurgent-controlled eastern Aleppo, the dynamic of resistance will have to change to guerrilla warfare to keep the revolution alive. Govermental Syrian forces fire into the sky as they celebrate their victory against rebels in eastern Aleppo, Syria, Dec. 12,2016. The focus of the conflict will swing quickly to the neighboring Idlib province, says Gen. Salim Idris, a former commander-in-chief of the Free Syrian Army, who fears the loss of Aleppo will deal an irreversible blow to the status of what remains of moderate and more secular militias. After Aleppo, "the Assad forces will then focus west on Idlib province and then that will be the end," Idris said. Rebels lose territory The Syrian military claimed Monday that 98 percent of eastern Aleppo is in the hands of regime forces. And while there is some dispute about that -- independent monitors calculate 10 percent of the eastern half of the city still is occupied by insurgents -- it is clear rebels are now contained in a small pocket and likely won't be able to hold out in the face of overwhelming firepower for more than a few hours or, at best, a handful of days, say Western diplomats based in Turkey. Zakaria Malahefji, the political officer of the 3,000-member Fastaqim Kama Umirt, a militia aligned with the Free Syrian Army, estimated 85 percent of eastern Aleppo is in government hands.

The Syrian Observatory for Human Rights, a British-based group that receives on-the-ground information from a network of activists, says Assad forces are pushing into six remaining rebel neighborhoods, including Bustan al-Qasr and Souq al-Hal. "The battle for Aleppo has begun to enter the final phase," said the observatory's director, Rami Abdel Rahman. Syrian generals agree. "The battle in eastern Aleppo should end quickly," Gen. Zaid al-Saleh told Syrian state media in the recaptured Sheikh Saeed. "They [rebels] don't have much time. They either have to surrender or die." Fighting intensifies Advances Monday came after a ferocious overnight bombardment, civilians and rebel commanders in Aleppo told VOA in frequently interrupted communications. They likened the situation inside the rebel pocket to doomsday, saying there's little help now for the wounded, with many injured buried under rubble. The White Helmets, a first responders group which accused the Assad regime of dropping chlorine-filled bombs over the weekend, says there are dozens of civilian casualties and rescuers can't move because of the frequency of the shelling and airstrikes. Journalists in government-held neighborhoods confirmed that shelling of rebel areas was nonstop overnight.

Syrian state television showed pictures of devastation with collapsed buildings and dead bodies in the streets. Dazed civilians, many of them women and children, carried bundles. Fatemah, who along with her seven-year-old daughter, Bana Alabed, has been tweeting since September 26 from a rebel-held district, posted Monday: "Final message - people are dying since last night. I am very surprised I am tweeting right now & still alive. - Fatemah." FILE - Bana Alabed, 7, and her mother have been tweeting about fighting in their hometown of Aleppo, Syria, Sept. 26, 2016. On Sunday, Fatemah tweeted: "The army is so near now. I don't know what to do. only way to flee is to regime side which I fear coz they will kill me." Pro-opposition activists working for the local news site Aleppo 24 alleged that regime forces executed 70 people, included seven women, Monday in the al-Fardous district after it was captured from rebels. VOA is unable to verify the claim. That report was among several alleging that summary executions are being carried out in districts overrun by regime militiamen. Jan Egeland, who heads the Norwegian Refugee Council and leads an international task force on humanitarian access to Syria, tweeted later that the Syrian and Russian governments "are accountable for any and all atrocities that the victorious militias in Aleppo are now committing!" Few ways out Many civilians are fleeing, some following rebel fighters into the districts they still occupy, but most heading to government-controlled west Aleppo. The Russian Defense Ministry said 13,346 civilians left rebel-controlled districts in the past 24 hours. It also claimed 728 rebels surrendered.

Syria's official SANA news agency said more than 3,500 people fled Sheikh Saeed at dawn as regime militiamen moved into the district. The Syrian Observatory said in the past month at least 415 civilians, including 47 children, had been killed in rebel-held territory, with hundreds injured. The group said 364 rebel fighters were killed. Opposition activists and civilians say regime forces are arresting and rounding up males, including medics and aid workers, who are fleeing eastern Aleppo, accusing them of supporting or being active in the rebel militias. Other young males are being press-ganged into army units and sent east to fight, according to opposition activists. "The Russians are not willing to negotiate safe passage and are stubborn about the evacuation of civilians even," said Zakaria Malahefji of the Fastaqim Kama Umirt militia. There is increasing bitterness in rebel ranks at what they see as an abandonment of their cause by the West. Opposition politicians remain furious at recent comments by U.S. Secretary of State John Kerry, who blamed them for the failure of cease-fire negotiations, accusing them of not wanting a pause in fighting.
