(CNN) โ More than a dozen aid workers have been killed or gone missing in Gaza over the past few days, several groups say, as Israelโs complete blockade of humanitarian aid neared the one-month mark amid its renewed military assault on the Palestinian enclave.
The United Nationsโ agency for Palestinian refugees, UNRWA, said Thursday eight of its staff had been killed in Gaza over the past week, while the Palestine Red Crescent Society (PRCS) said nine of its emergency medical technicians (EMTs) have been missing since Sunday following an incident in which Israeli forces fired on ambulances and fire trucks in the southern Gaza governorate of Rafah.
The Israel Defense Forces (IDF) has said that it fired on the ambulances and fire trucks in Rafah because they were being used as cover by Hamas and Palestinian Islamic Jihad fighters.

In a separate incident, Israeli strikes near a community kitchen in Gaza on Thursday killed a World Central Kitchen (WCK) volunteer and injured six others โas meals were being distributed,โ according to the US-based non-profit.
In response, the IDF told CNN that the WCK incident is under review.
โThe IDF is in contact with the organization to verify the details thoroughly,โ it added in a statement.
The attacks came after Israel renewed attacks across the strip on March 18, breaking a weeks-long ceasefire with Hamas. Since then, at least 921 Palestinians have been killed and 2,054 others injured, Gazaโs Ministry of Health reported Saturday.

The news also follows Israelโs decision before the ceasefire collapsed to block humanitarian aid from entering the enclave, in what it described as a move to pressure Hamas into accepting new terms for an extension of the ceasefire rather than proceed with phase two of the truce.
The UN and aid groups accuse Israel of violating international law by blocking the flow of aid into Gaza and of using starvation as a weapon of war. The same organizations have accused Israel of restricting or creating hurdles to the entry of aid throughout the war.
Noting the deaths of the UNRWA staff, the agencyโs Commissioner-General Philippe Lazzarini called Thursday for the ceasefire to resume and for Israel to lift its blockade on aid.
โNo humanitarian aid has entered Gaza for more than three weeks now,โ Lazzarini said, noting that before the ceasefire collapsed between 500 and 600 aid trucks had been entering the strip on a daily basis.
โThis is longest that Gaza has been without any supplies since the war began,โ Lazzarini said.
Israel launched its war in Gaza following Hamasโ October 2023 attack in which militants killed 1,200 people and took 251 hostage. Since then, Israelโs military campaign has killed more than 50,200 Palestinians and injured more than 114,000 people, the health ministry in Gaza says.
With the return to hostilities, hundreds of thousands of Palestinians in Gaza are once again at risk of โsevere hunger and malnutrition,โ the World Food Programme (WFP) warned in a statement on Thursday, stressing that its food stocks are enough to support its operations for a maximum of two weeks.
About 10 community kitchens were forced to close in Gaza since the ceasefire collapsed โdue to hostilities and energy shortages,โ according to the UN Office for the Coordination of Humanitarian Affairs (OCHA) on Tuesday. The office also warned that supplies of cooking gas were available โonly in extremely limited quantities at exorbitant prices,โ leaving families with few options aside from the community kitchens.
UNRWAโs Lazzarini said parents are unable to find food for their children, hunger is increasing and the risk of disease is spreading.
โThe siege must be lifted and crossings must re-open for a standard flow of humanitarian aid and commercial supplies,โ Lazzarini said.
About 400 aid workers, including teachers, doctors and nurses, have been killed in Israeli attacks in the enclave since October 7, 2023, OCHA said in an update earlier this week.
The death toll includes 289 UN staff and 34 PRCS workers as well as 76 from other NGOs.
EMTs and Civil Defense workers missing
According to the Palestine Red Crescent Society, its EMTs went missing in the Tel Sultan area of Rafah โafter being besieged and targeted by Israeli forcesโ on Sunday.
It said its teams were only able to start searching for the missing staff on Thursday as it had previously been denied access to the area.
Gazaโs Civil Defense said that six of its staff also went missing after being dispatched to the same area last weekend following what it described as a โsudden incursion by the Israeli occupation forces, the killing and injuring of dozens, and the besiegingโ of PRCS vehicles.
The PRCS said they had recovered the body of one of the Civil Defense team members on Thursday.
The Gaza Civil Defense said it had encountered scenes of devastation in Rafah while searching for a team of missing emergency workers.
Civil Defense spokesperson Mahmoud Basal said Friday that the body of one emergency worker who was among a nine-strong team that went to Rafah on Sunday had been found.
Basal said that when Civil Defense and Red Crescent teams were finally granted access to the area they found โmassive destructionโ and widespread bulldozing.
โWe found our vehicles and the Red Crescent vehicles destroyed,โ and subsequently the body of one worker that had been buried by bulldozers was retrieved, Basal said.
The Israeli military told CNN its forces had opened fire at โsuspicious vehiclesโ advancing toward troops without prior coordination, headlights or emergency signals during an operation against Hamas and Palestinian Islamic Jihad militants in southern Gaza last Sunday.
It said that it had โeliminated a number of Hamas and Islamic Jihad terroristsโ by firing on the vehicles and condemned what it claimed was โthe repeated use of civilian infrastructure by the terrorist organizations in the Gaza Strip, including the use of medical facilities and ambulances for terrorist purposes.โ
Since the start of Israelโs war in Gaza in October 2023, 19 PRCS members have been killed while on duty, according to the society.
โWe cannot bear to add more names to this tragic list,โ a spokesperson for the society said Thursday. โ(We call) on the international community to take serious measures to protect our medical teams.โ
The society said the search and rescue operation would resume Friday.
Volunteer killed as meals handed out
The World Central Kitchen said Israeli strikes near a community kitchen in Gaza on Thursday killed one of its volunteers and injured six others โas meals were being distributed.โ
โOur hearts are heavy today as we mourn the loss of one of our volunteers in Gaza,โ WCK said in a statement.
In April 2024, a series of Israeli military strikes killed seven WCK staffers in Gaza, drawing international condemnation and prompting a rare public acknowledgment from Israeli Prime Minister Benjamin Netanyahu and a promise to investigate the โtragic incident.โ
The US-based non-profit that focuses on fighting hunger around the world vowed Thursday to continue its work in the strip.
โWe will continue to support community kitchens throughout the region and operate our field kitchens where possible, based on daily assessments,โ it said in a statement. โWe hope for peace for all and a lasting ceasefire.โ
