United Nations, May 15 (RHC)-- The United Nations says it had informed Israel’s authorities of the movements of a clearly marked UN convoy that came under attack by the regime's military forces in Rafah on Monday.

An international staff member, identified as Col Waibhav Kale, was killed and another one injured, when Israeli forces attacked the convoy that was on its way from Rafah to the European Gaza Hospital in Khan Younis.

In a statement on Tuesday, UN spokesperson Rolando Gomez said: “The UN informs Israeli authorities of the movement of all of our convoys.”  “This is a standard operating procedure,” he said.

“This was the case yesterday [Monday] morning, so we have informed them.  And it was a clearly marked UN vehicle.”  Gomez said the attack against the UN convoy “is a sheer illustration that there’s really nowhere safe in Gaza at the moment.”

UN Secretary-General Antonio Guterres had called for a full investigation, according to Gomez.  “Of course we want accountability.  This is the ultimate aim of this investigation.  International humanitarian workers are not targets, so such attacks must end.”

Six international aid workers and a Palestinian colleague from the international food charity World Central Kitchen were killed in an Israeli strike in April in Gaza, after having given coordinates to the Israeli military.

Israel has killed more than 35,090 people since it launched its bloodiest-ever military campaign in Gaza in October.

In the occupied West Bank, Israeli forces shot a volunteer paramedic in the leg on Tuesday.  Hamza Jetawi, who is working with the Palestine Red Crescent Society (PRCS) said he was shot while responding to reported injuries in Nour Shams refugee camp.   He said Israeli forces blocked an ambulance from picking him up for treatment for more than 12 hours.
