Israel's move to prevent all aid from entering the Gaza Strip after Hamas reportedly refused to accept a plan to continue with phase one of the fragile ceasefire has had an immediate impact, including a 100-fold increase in the price of flour and vegetables.
That's according to the UN aid coordination office, OCHA , which said on Monday that the Kerem Shalom, Erez and Zikim crossing closures means that vital humanitarian assistance, including thousands of tents, can't be delivered to civilians in need.
Phase one of the ceasefire mediated by Egypt, Qatar and the US expired on Saturday, with Hamas calling on Israel to move on to the next agreed phase - but Israel is calling instead for a continuation of phase one through the end of the Holy Month of Ramadan in line with a proposal from the top US envoy to the region.
January's ceasefire deal has seen the release of 33 Israeli hostages who've been held captive since the 7 October terror attacks, with around 1,900 Palestinian prisoners exchanged.
"The ceasefire has provided the opportunity to distribute food, to distribute water, as well as shelter assistance and medical aid, allowing nearly everyone in Gaza to receive food parcels," said UN Spokesperson Stéphane Dujarric, briefing reporters in New York.
"Our humanitarian partners tell us that following the closure of the crossings into Gaza yesterday, flour and vegetable prices increased more than 100-fold. Partners are currently assessing the stocks that are currently available," he added.
Ceasefire, 'a critical lifeline': UNICEF
The UN children's agency, UNICEF , warned that the stoppage of aid deliveries into Gaza will quickly lead to devastating consequences for children and families who are simply struggling to survive.
"The aid restrictions announced yesterday will severely compromise lifesaving operations for civilians," said Edouard Beigbeder, UNICEF Regional Director for the Middle East. "It is imperative that the ceasefire - a critical lifeline for children - remains in place, and that aid is allowed to flow freely so we can continue to scale up the humanitarian response."
The agency said that between 19 January and last Friday, almost 1,000 UNICEF trucks had crossed into the enclave carrying clean water, medical supplies, vaccines, therapeutic food and other materials.
Since the start of the ceasefire on 19 January, UNICEF and partners have provided warm clothing to 150,000 children in Gaza and increased daily water distribution for nearly half a million people living in more remote areas, Mr. Dujarric said.
Nearly 250,000 children and thousands of pregnant and breast-feeding mothers have received nutritional supplements since the ceasefire took effect.
Over the past two weeks, in Rafah, Khan Younis and Deir al Balah, aid partners have distributed vegetable seed kits for gardening to try and encourage more diverse diets.
Around 1,500 water distribution points are now operating across Gaza - double the number operational at the start of the ceasefire. "However, partners tell us that pipes and spare parts for maintenance are urgently needed," said Mr. Dujarric.
Classrooms open
Across Gaza, more than 100 public schools have reopened, allowing around 100,000 students back into the classroom.
In Gaza City and North Gaza, UN partners will use tents to ensure children can continue learning, with some wood pallets recycled into school furniture.
OCHA teams visited a displacement site in Khan Younis on Monday where around 1,200 people are staying. These communities have not been allowed to return to their homes, which are located in the buffer zone.
OCHA is working to mobilise assistance to meet their needs.
Meanwhile in the occupied West Bank, OCHA reports that ongoing operation by Israeli forces continues to drive humanitarian needs in northern areas. Humanitarian partners continue to face movement restrictions.
