United Nations aid agencies have warned that dwindling food and fuel stocks could force aid operations in Gaza to grind to a halt within days as vital crossings remain shut, forcing hospitals to close down and leading to more malnutrition, Reuters reports.

Humanitarian workers have sounded the alarm this week over the closure of the Rafah and Kerem Shalom crossings for aid and people as part of Israel’s military operation in Rafah, where around 1 million uprooted people have been sheltering.

“For five days, no fuel and virtually no humanitarian aid entered the Gaza Strip, and we are scraping the bottom of the barrel,” said the Unicef Senior Emergency Coordinator in the Gaza Strip, Hamish Young.

“This is already a huge issue for the population and for all humanitarian actors but in a matter of days, if not corrected, the lack of fuel could grind humanitarian operations to a halt,” he told a virtual briefing.

More than 100,000 people have fled Rafah in the last five days, he added.
