Footage shared on social media Tuesday showed newborn babies being evacuated from a burning hospital in Maarrat al-Nu'man, Syria, after Russia carried out a series of air strikes on Sunday.

Civil defense workers are seen being rushed out of the hospital in stretchers while other rescuers scramble to extinguish the flames engulfing the hospital building. The video, recorded by emergency responders, showed a small child being pulled out of the rubble of a building.

Maarrat al-Nu'man was one of the cities targeted by Russian-allied-Syrian government forces because it was believed to be a rebel-held stronghold. Al Nouman Central Hospital in the city was attacked by four airstrikes, following which, several medical facilities went out of power, the National reported. 

The Union of Medical Care and Relief Organisations (UOSSM) reported that a number of newborn babies were “temporarily suffocated” when their incubators stopped working. 

Russian airstrikes also intensified on the Syrian cities of Saraqeb and Idlib and the towns of Kafr Nubl and Maasran, a day after rebels shot down a Russian jet, killing its pilot.

“We are pulling bodies from under collapsed walls,” said Ahmad Hilal, a civil defense rescuer, NBC News reported. “The Russians are taking their revenge on civilians, many of whom were already displaced and had fled their homes from earlier bombardment.”

As many as 150 airstrikes were conducted by Russia on Idlib province, between Sunday and Monday. Chlorine bombs were reportedly used during the attacks, which claimed the lives of several civilians, leaving several others gravely injured.

According to the Syrian Observatory for Human Rights, the bodies of at least 11 people, including children, were recovered from the debris around Idlib city.

The UN’s International Commission of Inquiry on Syria condemned the attacks, which cause collateral damage among the very people the government of Syria swore to protect.

“Over the last 48 hours, the scale and ferocity of attacks [in Idlib and Eastern Ghouta] increased dramatically resulting in multiple reports of civilian casualties and airstrikes that have reportedly hit at least three hospitals,” the commission said in a statement Tuesday.

“These reports are extremely troubling and make a mockery of the so-called ‘de-escalation zones’ intended to protect civilians from such bombardment,” commission’s chair Paulo Pinheiro said.
