As Aleppo Falls, Residents Express Sorrow and Fear Waiting to Leave

— -- With the fall of eastern Aleppo — the last opposition stronghold in a major Syrian city — many feel the Syrian revolution is over.

Under an agreement reached yesterday, civillians and rebels were supposed to be able to leave for other areas of the country.

Evacuations were planned for Wednesday, to allow safe passage to other opposition-held areas in the northern or western countryside of Aleppo, although the exact details remained unclear.

But on Wednesday, the cease-fire was broken. Residents said artillery shells have continued to be fired on eastern Aleppo neighborhoods since the morning. The evacuation was postponed, opposition sources told ABC News.

The U.N. has expressed concern about men who have reportedly gone missing after leaving opposition-held areas of Aleppo for government-controlled areas recently. They have also condemned the apparent breakdown, with reports that at least 82 civilians, including 11 women and 13 children, have been killed by government forces and their allies.

"While some reportedly managed to flee yesterday, some were reportedly caught and killed on the spot, and others were arrested," U.N. spokesman Rupert Colville told reporters in Geneva on Tuesday.

On Tuesday, Russia announced that the Syrian government had gained full control of eastern Aleppo and that fighting had stopped. The U.N. said that an estimated 50,000 civilians and some 1,500 rebel fighters remained in eastern Aleppo neighborhoods.

But even if given the opportunity, several residents said they will be sad to leave.

"Since Aleppo has fallen, there is no revolution left in Syria," Abdulkarim Sergieh, an anti-government media activist, told ABC News via voice recording in Arabic. "For that reason, I am not going to stay in a different area in Syria. I am going to leave the country."

Sergieh was born and raised in Aleppo. In 2012, he moved to the eastern part of his city as opposition forces gained control of the area, he said. He stayed — despite years of regular bombardments and months of bitter siege with little access to water, food, electricity and fuel for heating. Now he plans to leave — not just the city but the country.

He said he plans to move to Turkey first and then see where he will go from there.

"It is a feeling that can’t be described. It will be like a fish leaving water," Sergieh said. "I already feel alienation now just by the thought of leaving the city."

A lawyer in eastern Aleppo, Hassan Dahhan, also expressed dismay at leaving his city.

"Having to leave the place that I lived in all my life makes my heart bleed," Dahhan told ABC News in a text message in Arabic on Tuesday. "My only fault is that I said no to the government. Many of my friends have been killed. My house was destroyed and I have been displaced." His family lives outside of Aleppo and he hasn’t seen his children for about a year, he said.

"Honestly, I haven’t decided where I will go," Dahhan said. He said he was born in the old city of Aleppo and lived there all his life. Earlier, he had told ABC News that he was hoping for an opportunity to leave for other rebel-held areas because he believed that the Syrian government would detain him in their territories. But leaving would still be difficult.

Monther Etaky, an anti-government activist who also remains in eastern Aleppo with his wife and 5-month old son, described the thought of leaving as painful.

"Leaving this city will be difficult for me, but we don’t have a choice," he told ABC News in a voice recording. "We have our families and other civilians and have to think about them."

He added that he and the other residents of eastern Aleppo will need protection from the international community and organizations in order to leave because they can’t trust the Syrian government.

Before the war, Aleppo was Syria’s largest city with a population of two million. The city had been divided into the rebel-held east and the government-held west since 2012. In recent months, the Syrian government, with help from its Russian and Iranian allies, intensified its airstrikes on eastern Aleppo and tightened the siege in an attempt to gain full control of the area, rebel held until recently. Gaining control of the eastern neighborhoods is a strategic victory for President Bashar al-Assad.
