Pro-government forces advanced into the Syrian city of Aleppo this week, entering homes and killing civilians. At least 82 Syrians were killed Monday alone, according to an estimate made by United Nations. The UN reported that bodies littered the streets and residents were unable to retrieve them due to continued bombardment and shooting.  The International Rescue Committee released a statement on the devastating situation in the region Tuesday. 

“Eastern Aleppo has become a bloody graveyard for thousands of innocent people and for the death of respect for international law and the rules of war,” said David Miliband, president and CEO of the committee. “We’ve seen countless attacks on the homes of civilians, institutions created for good like hospitals and schools bombed and destroyed, plus reports from the UN of families being shot in cold blood.”

Syrians took to social media to post “last goodbye” messages as the bombardment continued. Others pleaded with people to protest at the UN to stop the massacre. 

“This could be my final appeal … everybody that can send a message to his government, to his country … ask him to stop the aggression, stop the killing, stop the war,” Salim Abu Al-Nassar, a dentist in eastern Aleppo, posted in a video shared on social media Tuesday.

The troops are backing Syrian President Bashar Assad. Conflict in Syria has escalated since 2011 after protests known as the Arab Spring divided the nation. Russia began bombing Syria in 2015 to back the government. 

“The crushing of Aleppo, the immeasurably terrifying toll on its people, the bloodshed, the wanton slaughter of men, women, and children, the destruction,” said UN High Commissioner for Human Rights Zeid Ra’ad Tuesday. “And we are nowhere near the end of this cruel conflict.”
