Amid Israel’s complete blockade of the besieged territory, a group of independent United Nations (UN) experts on Thursday deplored that relentless strikes against Gaza amounted to “collective punishment,” as the death toll in the region surged past 1,300 with the war entering its sixth day on Thursday. Israel said on Thursday there would be no humanitarian break to its siege of the Gaza Strip until all its hostages were freed after the Red Cross pleaded for fuel to be allowed in to prevent overwhelmed hospitals from “turning into morgues”. Israel has vowed to annihilate the Hamas movement that rules the Gaza Strip in retribution for the deadliest attack on Jews since the Holocaust, when hundreds of gunmen poured across the barrier fence and rampaged through Israeli towns on Saturday. Public broadcaster Kan said the Israeli death toll had risen to more than 1,300 people killed since Saturday. Most were civilians gunned down in their homes, on the streets or at a dance party. Scores of Israeli and foreign hostages were taken back to Gaza. Israel has responded so far by putting the enclave, home to 2.3 million people, under total siege and launching by far the most powerful bombing campaign, destroying whole neighbourhoods. Gaza authorities report 1,354 people have been martyred and 6,049 people have been wounded in the bombing. The sole electric power station has been switched off and hospitals are running out of fuel for emergency generators. Israeli Energy Minister Israel Katz vowed his country would not allow basic resources or humanitarian aid into Gaza until Hamas released the hostages it took during its surprise weekend attack on Israel after the United Nations (UN) called for allowing humanitarian aid into the besieged territory. “Humanitarian aid to Gaza? No electric switch will be turned on, no water tap will be opened and no fuel truck will enter until the Israeli abductees are returned home,” he said in a statement. While condemning the “horrific crimes committed by Hamas”, the group of independent UN experts said that Israel had resorted to “indiscriminate military attacks against the already exhausted Palestinian people of Gaza,” Reuters reported. “They have lived under unlawful blockade for 16 years, and already gone through five major brutal wars, which remain unaccounted for,” the group, which includes several UN special rapporteurs, said in a statement. “This amounts to collective punishment. There is no justification for violence that indiscriminately targets innocent civilians, whether by Hamas or Israeli forces. This is absolutely prohibited under international law and amounts to a war crime.” United Nations Secretary-General Antonio Guterres called for allowing humanitarian aid into war-struck Gaza, with the death toll in the region surging past 1,3000 as the war enters its sixth day on Thursday. Days after Israel announced a total blockade of Gaza, The UN chief took to X, formerly known as Twitter, saying the supply of humanitarian aid, including food and water, “must be allowed” into Gaza. “Crucial life-saving supplies – including fuel, food and water – must be allowed into Gaza. We need rapid and unimpeded humanitarian access now,” the UN chief wrote on X.
