A hospital employee known as Moudhar told CNN that staff members were evacuating the wounded after the first strike on the Women and Children's Hospital when the complex and a road leading to the Turkish border were struck again. Women and children were among the dead, he said.

In a separate attack, a hospital supported by Doctors Without Borders at Maarat al-Numan in Syria's Idlib province was destroyed after being struck four times within minutes, the medical humanitarian organization said.

Images from the scene showed the hospital reduced to mostly twisted metal and other rubble.
