Israel on Saturday hit parts of Gaza including Rafah where it expanded an evacuation order, as the UN warned an outright invasion of the crowded city risked an “epic” disaster.AFP journalists, medics and witnesses reported strikes across the coastal territory, where the UN says humanitarian relief is blocked after Israeli troops defied international opposition and entered eastern Rafah this week.That effectively shut a key aid crossing and suspending traffic through another.At least 21 people were killed during strikes in central Gaza and taken to Al-Aqsa Martyrs Hospital in Deir al-Balah city, a hospital statement said.Bodies covered in white dust lay on the ground in a courtyard of the facility. A man in a baseball cap leaned over one body bag, clasping a dust- covered hand that protruded.The feet of another corpse poked from under a blanket bearing the picture of a large teddy bear.In Rafah, witnesses reported intense air strikes near the crossing with Egypt, and AFP images showed smoke rising over the city. Other strikes occurred in north Gaza, witnesses said.Hamas on Saturday accused Israel of “expanding the incursion into Rafah to include new areas in the centre athe west of the city”. Israeli troops on Tuesday seized and closed the Palestinian side of the Rafah crossing — through which all fuel passes into Gaza — after ordering residents of eastern Rafah to evacuate. The army said Saturday troops were fighting “armed terrorists” at the crossing and had found “numerous underground tunnel shafts”. – Truce deal hopes fade – The war began with Hamas’s unprecedented October 7 attack on Israel, which resulted in the deaths of more than 1,170 people, mostly civilians, according to an AFP tally of Israeli official figures.During their attack, militants also seized hostages. Israel estimates 128 of them remain in Gaza including 36 who the military says are dead.Israel’s retaliatory offensive has killed at least 34,971 people in Gaza, mostly women and children, according to the Hamas-run territory’s health ministry.While mediation efforts towards a truce and hostage release appeared to stall, Hamas’s armed wing said a hostage who appeared in a video it released earlier on Saturday had died from wounds suffered in an Israeli strike.The Ezzedine Al-Qassam Brigades said Nadav Popplewell, a British-Israeli man, had been wounded in a strike a month ago and died “because he did not receive intensive medical care because the enemy has destroyed the Gaza Strip’s hospitals”. The Israeli military did not offer any comment on the earlier video and AFP was unable to independently verify its authenticity.US President Joe Biden on Saturday said a ceasefire would be achieved “tomorrow” if Hamas released the hostages. – ‘What next?’ – The new evacuation order for eastern Rafah, posted on X by Israeli military spokesman Avichay Adraee, said the designated areas had “witnessed Hamas terrorist activities in recent days and weeks”. Military spokesman Daniel Hagari later said “we have eliminated dozens of terrorists in eastern Rafah”. Israel on Saturday said 300,000 people had fled Rafah since an initial evacuation order, as more residents piled water tanks, mattresses and other belongings onto vehicles and prepared to flee again. “We don’t know where to go,” said Farid Abu Eida, who was preparing to leave Rafah, having already been displaced there from Gaza City. “There is no place left in Gaza that is safe or not overcrowded… There’s nowhere we can go.”Journalists as well began dismantling their tents and packing their equipment to leave the city. “Where to? After Rafah there is expulsion, not displacement. This is the question that Palestinians ask, what next?” said journalist Nabil Diab. The evacuation order on Saturday told residents to go to the “humanitarian zone” of Al-Mawasi, on the coast northwest of Rafah.That area has “extremely limited access to clean drinking water, latrines” and other basic services, said Sylvain Groulx, Doctors Without Borders (MSF) emergency coordinator in Gaza. EU chief Charles Michel said on social media that Rafah civilians were being ordered to “unsafe zones”, denouncing it as “unacceptable”.- ‘Humanitarian catastrophe’ -A US State Department report on Friday said it was “reasonable to assess” that Israel had violated norms on international law in its use of weapons from the United States, but did not find enough evidence to block shipments. The State Department submitted its report two days after Biden publicly threatened to withhold certain bombs and artillery shells if Israel went ahead with an all-out assault on Rafah, where the United Nations says 1.4 million have been sheltering. Hamas in a statement said Israel’s “continued control” and closure of the Rafah crossing exacerbate the “humanitarian catastrophe” in the besieged territory.Israeli Prime Minister Benjamin Netanyahu has pledged to “eliminate” Hamas mbattalions in Rafah after the army in January said it had dismantled the militant group’s command structure in northern Gaza.But on Saturday Adraee said Hamas “is trying to rebuild” there and ordered evacuations from the north’s Jabalia refugee camp and Beit Lahia areas.UN Secretary-General Antonio Guterres said on Friday that Gaza risked an “epic humanitarian disaster” if Israel launched a full-scale ground operation in Rafah.The Israeli army said it had reopened the Kerem Shalom crossing near Rafah on Wednesday, but aid agencies cautioned that getting assistance through the militarised area remained extremely difficult.The army said Saturday that rockets had been fired at the crossing, but reported no injuries.Israel has said its Erez crossing into northern Gaza remains open.On Friday the White House said it did not yet see a “major ground operation” in Rafah but was watching the situation “with concern”.Biden’s administration had already paused delivery of 3,500 bombs as Israel appeared ready to invade Rafah.In New York, the UN General Assembly voted overwhelmingly to grant the Palestinians additional rights in the global body and backed their drive for full membership, vetoed by Washington at the Security Council.
