Doctors Without Borders (MSF) accused the Israeli entity of causing a deliberate humanitarian catastrophe in the Gaza Strip.
"We are witnessing, in real time, the creation of conditions for the eradication of Palestinian lives in Gaza," MSF said in a statement stressing that Gaza has become a hell on earth for Palestinians.
MSF said that its medical teams in Gaza City have seen a 32 percent increase in the number of patients presenting with malnutrition over the past two weeks.
Health facilities that still function - already critically inadequate in number and capacity for the population - are still being attacked and are suffering from rapidly diminishing stocks of medications and other essential supplies, MSF said, pointing out that its teams in Gaza have received no supplies for 11 weeks and face critical shortages of essential medical items such as sterile compresses and sterile gloves.
The MSF firmly rejected the US-Israel proposition to control the distribution of supplies in Gaza, under the guise of humanitarian aid raises grave humanitarian, ethical, security and legal concerns.
"Making aid conditional on forced displacement and vetting of the population is another tool in the ongoing campaign of ethnic cleansing of the Palestinian population," MSF warned.
"MSF firmly rejects and condemns any plan that further reduces availability of aid and subjugates it to Israeli military occupation objectives," it said.
MSF called on UN, EU member states, and all those with influence over Israel to urgently use their political and economic leverage to stop the instrumentalisation of aid.
