Held by rebels since 2012, pro-government forces backed by Russia have waged an intense battle to reclaim the city in recent months.
Almost 600 civilians, more than 100 of them children, have been killed in the city since mid-November, according to a report by the Syrian Observatory for Human Rights cited by Al Jazeera. At least 463 of the civilian deaths, including 62 children, were killed by government forces in the eastern part of the city.
An evacuation deal was struck late on Tuesday as government forces seized most of Syria's largest city, but it did not hold, and bombings and violent clashes continued. According to the U.N., civilians were likely being killed in summary executions by pro-government forces. Approximately 80,000 civilians were said to be trapped in the few miles of eastern Aleppo held by rebels, and UNICEF says that 100 unaccompanied children were trapped in a building under heavy attack, according to Al Jazeera.
As President Bashar al-Assad lauded the fall of Aleppo as "the writing of history," the Guardian reported that 951 people have been escorted out of the city and that Turkey is promising to evacuate 50,000 more over the next three days.
As the evacuation began, Jan Egeland, secretary general of the Norwegian Refugee Council and head of the U.N. task force on humanitarian access in Syria, took to Twitter to criticize the international community's response to the horrors of the crisis.
While what's next for the city is unclear, there are still ways you can help the victims of the crisis in Aleppo and Syria, as well as refugees from the Syrian civil war. Here are some organizations working in Syria to help victims of the humanitarian crisis.

On Monday, UNICEF released a statement calling on the world to "stand up for the children of Aleppo and bring their living nightmare to an end." The organization promised to provide assistance for evacuating residents.
Juliette Touma, the children's charity's regional chief of communication for the Middle East and Northern Africa, told NBC on Tuesday that perhaps 100,000 civilians had been trapped in the city in conditions that had even experienced aid workers stunned.
"I'm not sure I have the words to start describe the situation, for children in particular," Touma said.
On Thursday, as evacuations got underway, the Independent posted a video showing a group of children in the war-ravaged city pleading to be rescued and for peace.
