The unrelenting war in Gaza hasn't spared hospitals, their staff or the people sheltering there, the UN World Health Organization (WHO) said on Friday as it unveiled data indicating more than 350 attacks on healthcare in the enclave since hostilities erupted. A total of 645 people have died since Oct. 7 and another 818 were injured as a result of these incidents, said WHO spokesperson Tarik Jasarevic, his comments coming amid allegations that a nurse was shot and critically injured while inside an operating theater at a hospital in Khan Younis. "These attacks have affected 98 healthcare facilities, including 27 hospitals damaged out of 36, and affected 90 ambulances, including 50 which sustained damage," Jasarevic told journalists in Geneva. In its latest update on the crisis, the UN aid coordination office, OCHA, reported more "intense fighting" in Khan Younis in southern Gaza on Thursday involving shelling and heavy gunfire. Citing UN partner the Palestinian Red Crescent Society (PCRS), the UN aid coordination office said that Nasser Hospital and Al Amal Hospital — reportedly under siege for 17 days — had continued to be particularly badly affected by the violence which "is driving thousands of people" from the city further south to Rafah. The OCHA update also relayed reports from the Gazan health authority of continuing "allegations of sniper shooting in the vicinity of Nasser Hospital" and allegations that the Israeli military had prevented the movement of ambulances and access to the facility. "On Feb. 8, a nurse was reportedly shot and critically injured while inside the operations room in Nasser Hospital and two Palestinians were reportedly shot and killed in the vicinity," the OCHA update said. "On Feb. 7, a Palestinian woman was reportedly shot and killed while purportedly fetching water from Nasser Hospital." The latest WHO data also highlighted the growing number of attacks on healthcare in the occupied West Bank since the Gaza-Israel war erupted on Oct. 7, after widely condemned Hamas-led terror attacks left 1,200 Israeli and foreign nationals butchered and more than 250 taken hostage. Some 364 attacks on healthcare have happened in the West Bank, resulting in 10 fatalities and 62 injuries, Jasarevic said. He noted that 44 health facilities had been affected, including 15 mobile clinics and 24 ambulances. The latest toll from the fighting in Gaza is at least 27,840 fatalities with more than 67,300 injured, according to the local health authority. As of Feb. 8, 225 Israeli soldiers have been killed with 1,314 injured in Gaza since the beginning of the ground operation, according to the Israeli military. UN humanitarians continued to highlight that the risk of famine in Gaza is increasing "by the day", particularly in northern Gaza. Hundreds of thousands of people there have been "predominantly cut off from assistance", OCHA said, despite the fact that this is where the greatest needs are, with many reportedly grinding animal feed to make flour. Since the onset of the crisis, the UN World Food Program (WFP) has delivered 1,940 trucks — 19 percent of all aid trucks, it said — carrying over 32,413 tons of lifesaving food supplies. The last time the UN agency for Palestinian refugees, UNRWA, was able to carry out a food distribution in the north of Wadi Gaza was Jan. 23, OCHA's update noted. And as UN humanitarians reiterated deep concerns on Friday about any further escalation of fighting in overcrowded Rafah in the far south of the Gaza Strip, the UN human rights office, OHCHR, insisted that any reported attempt by Israel to create a "buffer zone" with Gaza could constitute a war crime. "Article 53 of the Geneva Convention prohibits destruction by the occupying power of property belonging to private persons, except where such destruction is rendered absolutely necessary by military operations," said OHCHR spokesperson Marta Hurtado. "Destruction carried out to create a buffer zone for general security purposes do not appear consistent with the ...military operations." Asked for a reaction to an Israeli counter-terrorism operation inside a West Bank hospital that left three Palestinian militants dead late last month, Hurtado noted that Israeli security forces had claimed that one of those targeted had a gun, " a claim denied by hospital staff. No exchange of fire was reported, she said, emphasizing that under applicable international human rights law, firearms may only be used when strictly necessary to prevent an imminent threat to life or serious injury and is otherwise unlawful. — UN News
