At least six newborn babies have died in Gaza due to severe cold, according to Dr Saeed Saleh, a health official at the Patient's Friends Benevolent Society Hospital (PFBS) in the enclave, in a recorded video on Tuesday.
Dr Saleh said that in the past two weeks, eight newborns were admitted with severe cold-related injuries, six of whom later died.
The hospital highlighted the dire living conditions facing Palestinians, who are currently residing in tents and bombed-out homes, with no protection from the freezing temperatures currently sweeping across the Middle East.
Health officials at the hospital called on mediators in the conflict between Israel and militant group Hamas to urgently provide mobile homes as temporary shelters for more than 280,000 families who are homeless after Israeli airstrikes.
They also called for fuel deliveries to ensure warmth and safeguard young children from the harsh weather conditions.
Israel and Hamas agreed on a ceasefire in Gaza on 19 January to end nearly 16 months of conflict and allow the release of Israeli hostages in exchange for Palestinian prisoners.
However, the truce is fragile with both sides accusing the other of violations. Last week, Hamas threatened to postpone the scheduled release of hostages after it said Israel had delayed the promised entry of mobile homes into the devastated strip.
Hamas blamed the deaths of the newborns on Israel's "criminal policies," accusing Israel of obstructing humanitarian aid.
Israel did not immediately comment on the reports of the newborn deaths. It has consistently denied restricting aid.
International aid officials have confirmed that aid is getting into Gaza despite logistical problems, but they warn more was needed.
WHO concerned over attacks in West Bank
The World Health Organization said it is deeply concerned about violence in the Israeli-occupied West Bank and the impact of "starkly rising" attacks on healthcare.
Israel sent tanks into the West Bank for the first time in more than 20 years on Sunday and ordered the military to prepare for an "extended stay" to fight Palestinian militant groups in the area's refugee camps.
"We are deeply concerned about the situation in the West Bank and the impact on health", Dr Rik Peeperkorn, WHO representative in the West Bank and Gaza, told reporters via video link from Gaza.
"We see the current flashpoints of violence, attacks on healthcare ... starkly rising in the West Bank."
The WHO says there have been 44 attacks this year that affected the provision of healthcare in the West Bank, with four healthcare facilities impacted.
Four patients died waiting for an ambulance and eight health workers were injured while attempting to reach patients, it said.
It also said 25 healthcare workers and patients had been killed and 121 injured in the West Bank from 7 October 2023 - the date of the deadly Hamas-led attack on Israel that started the Gaza war - to 14 February this year.
The WHO also reported "severe movement restrictions" across the West Bank, including obstacles affecting the movement of ambulances and access for healthcare workers.
The WHO has provided emergency supplies and trauma kits to some West Bank hospitals, Dr Peeperkorn said.
At least 40,000 Palestinians have left their homes in Jenin and the nearby city of Tulkarm in the northern West Bank since Israel began its operation last month after reaching a ceasefire agreement in Gaza after 15 months of war.
Eighty-two Palestinians were killed in the West Bank between 1 January and 13 February, according to the latest WHO figures.
