WASHINGTON: US President Donald Trump voiced optimism Friday about a new ceasefire in Gaza, as criticism grew over mounting civilian deaths at Israeli-backed food distribution centers in the territory.Asked by reporters how close a ceasefire was between Israel and Hamas, Trump said: “We think within the next week, we’re going to get a ceasefire.”The United States brokered a ceasefire in the devastating conflict in the waning days of former president Joe Biden’s administration, with support from Trump’s incoming team.Israel broke the ceasefire in March, launching new devastating attacks on Hamas, which attacked Israel on October 7, 2023.Israel also stopped all food and other supplies from entering Gaza for more than two months, drawing warnings of famine.Israel has since allowed a resumption of food through the controversial US- and Israeli-backed Gaza Humanitarian Foundation, which involves US security contractors with Israeli troops at the periphery.United Nations officials on Friday said the GHF system was leading to mass killings of people seeking aid, drawing accusations from Israel that the UN was “aligning itself with Hamas.”Eyewitnesses and local officials have reported repeated killings of Palestinians at distribution centers over recent weeks in the war-stricken territory.The Israeli military has denied targeting people and GHF has denied any deadly incidents were linked to its sites.But following weeks of reports, UN officials and other aid providers on Friday denounced a wave of killings of hungry people seeking aid.“The new aid distribution system has become a killing field,” with people “shot at while trying to access food for themselves and their families,” said Philippe Lazzarini, head of the UN agency for Palestinian affairs (UNWRA).“This abomination must end through a return to humanitarian deliveries from the UN including @UNRWA,” he wrote on X.The health ministry in the Hamas-controlled territory says that since late May, more than 500 people have been killed near aid centers while seeking scarce supplies.The country’s civil defense agency has also repeatedly reported people being killed while seeking aid.“People are being killed simply trying to feed themselves and their families,” said UN Secretary-General Antonio Guterres.“The search for food must never be a death sentence.”Medical charity Doctors Without Borders (MSF) branded the GHF relief effort “slaughter masquerading as humanitarian aid.”
