Israel's suspension of goods entering Gaza is taking a toll on the Palestinian enclave, with some bakeries closing and food prices rising, while a cut in the electricity supply could deprive people of clean water, Palestinian officials said.The suspension, which Israel said was aimed at pressuring resistance group Hamas in ceasefire talks, applies to food, medicine and fuel imports.The UN Palestinian refugees agency UNRWA said the decision to halt humanitarian aid threatens the lives of civilians exhausted by 17 months of "brutal" war. Most of Gaza's 2.3mn people were dependent on aid, it said.Hamas describes the measure as "collective punishment" and insisted it will not be pushed into making concessions.Abdel-Nasser al-Ajrami, head of the Gaza bakers' union, said that six out of the 22 bakeries still able to operate in the enclave had already shut after they ran out of cooking gas."The remaining bakeries may close down in a week or so should they run out of diesel or flour, unless the crossing is reopened to allow the goods to flow," he said.The bakeries were already unable to meet the needs of the people, he said.Israel last week blocked the entry of goods into the territory in a standoff over a truce that has halted fighting for the past seven weeks. The move has led to a hike in prices of essential foods as well as of fuel, forcing many to ration their meals.Israel's onslaught on Gaza has killed more than 48,000 Palestinians since October 2023, according to Gaza health officials, left most of its people destitute and razed much of the territory to the ground.In Israel's latest punitive measure, Energy Minister Eli Cohen said on Sunday he had instructed the Israel Electric Corporation not to sell electricity to Gaza in what he described as a means of pressure on Hamas to free hostages.Israel already cut power supply to Gaza at the war's start but this move would affect a wastewater treatment plant currently supplied with power, according to the Israeli electricity company.The Palestinian Water Authority said the decision suspended operations at a water desalination plant that produced 18,000 cubic meters of water per day for the population in central and southern areas of Gaza Strip."The decision is catastrophic, municipalities now will be obliged to let sewage water stream into the sea, which may result in environmental and health risks that go beyond the boundaries of Gaza," an official said.All the aid supplies being distributed by the Palestine Red Crescent are dwindling and it is having to ration what remains, the International Federation of Red Cross and Red Crescent societies said."If it is possible to find the basics like eggs and chicken, the prices have rocketed and are out of reach for the majority of people in Gaza," IFRC spokesperson Tommaso Della Longa said.It is also concerned that a lack of medical supplies and medicines may impact the treatment of patients.Underscoring the fragility of the ceasefire, an Israeli airstrike killed three Palestinians in the Bureij camp in central Gaza Strip, medics said.Mediators Egypt, Qatar and the US are trying to salvage the ceasefire deal.Israeli team heads to Qatar for talksIsrael's negotiating team left for Qatar Monday for talks aimed at extending the fragile Gaza ceasefire, AFP reports from Jerusalem. The first phase of the truce deal expired on March 1 with no agreement on subsequent stages that should secure a lasting end to the war. An Israeli official familiar with the negotiations said the country's team had left for Doha. Media reports said the delegation was led by a top official from the domestic security agency Shin Bet.
