Syrian activists are sharing a harrowing video that appears to show a neonatal ward in a bombed out hospital in the town of Azaz.

Reportedly filmed by a nurse on scene, the 30-second clip shows babies squirming and crying inside incubators, and rubble and machinery strewn on the concrete floor.

In the background, a high-pitched alarm wails and voices speak frantically.

The Paris-based organization Syria Charity shared the video on Twitter on Monday, along with a message in French.

"The first moments after the bombing," the translated tweet reads. "Not terrorists or fighters, only babies #CrimeAgainstHumanity."

It is unclear how many people died or were injured in the Azaz hospital airstrike.

According to an Associated Press report, the Syrian Observatory for Human Rights reported five casualties, including three children and a pregnant woman, and 30 injuries. Another activist told AP that 10 people were killed.

On Tuesday, World Vision confirmed that a bombing at a children's hospital had shattered windows and damaged the building's structure.

A press release from the organization said approximately 14 people were killed and 30 injured in the attack, which it said showed "blatant disregard for international humanitarian law."

"Recently there has been an alarming increase in attacks on hospitals, schools and other civilian areas in northern Syria," Fran Charles, the advocacy director for World Vision's Syria response said in the press release.

"Staff on-the-ground inside Syria report an increasingly restricted humanitarian space which means greater difficulty in reaching children and families with the assistance they so desperately need."

Other reports of attacks on hospitals and civilians also emerged this week.

An airstrike in the province of Idlib destroyed a clinic supported by Doctors Without Borders and left nine dead, while seven others died in an attack on a school.

Britain-based Syrian Observatory for Human Rights blamed Russian bombers for the deadly Idlib attack, AP reported, but Moscow denied the claim, calling it an "unsubstantiated accusation."

In response to the rise in violence against civilians, World Vision is calling on the international community to use diplomacy to stop the attacks and allow access to humanitarian aid.

The organization also urged countries to keep their borders open to refugees fleeing the deadly conflict.
