About 360 Israeli medical professionals, half of them doctors, have signed a letter demanding an investigation and prosecution of Israeli troops involved in the killing of 15 Palestinian emergency workers in Gaza, Al Jazeera cites the Israeli news outlet Haaretz.

“Killing rescue and medical personnel is a blatant violation of international law,” the letter states, according to the Haaretz report.

There has been international outcry and calls at the United Nations for a full and independent probe into what the Palestine Red Crescent Society said was the deliberate and targeted killing by Israeli forces of eight of its staff as well as six Palestinian Civil Defence workers. A ninth paramedic was taken prisoner.

The Israeli forces, who opened fire on the PRCS’s clearly marked ambulances and emergency vehicles, buried the evidence of their crimes — along with the bodies of the slain paramedics — in shallow pits.
