Gaza: Thousands of Palestinians attended the funeral on Saturday of a young female volunteer medic killed by the Israeli occupation regime in southern Gaza.

Razan Al Najjar, 21, a volunteer with the Gaza health ministry, was fatally shot in the chest near Khan Yunis on Friday.

Ambulances and medical crews attended the funeral, with her father holding the white blood-stained medics’ jacket she wore when she was shot, as mourners called for revenge.

Gazans have since March 30 staged border protests demanding the return of Palestinians to land they fled or were expelled from during the 1948 war surrounding Israel’s creation.

The UN envoy for the Middle East, Nickolay Mladenov, said in a tweet that “Medical workers are #NotATarget!” and that “Israel needs to calibrate its use of force and Hamas need to prevent incidents at the fence.”

The Palestinian Medical Relief Society said Najjar was shot “as she was attempting to provide first aid to an injured protester”, with three other first responders also hit by live fire on Friday.

“Shooting at medical personnel is a war crime under the Geneva conventions,” the PMRC said in a statement, demanding “an immediate international response to Israeli humanitarian law violations in Gaza”.
