Israeli tanks pushed into southern and eastern districts of the Gazan city of Deir al-Balah for the first time on Monday, an area where Israeli sources said the military believes hostages may be held. The area is packed with Palestinians displaced during more than 21 months of war in Gaza, hundreds of whom fled west or south after Israel issued an evacuation order, saying it sought to destroy infrastructure and capabilities of the Hamas.
Tank shelling in the area hit houses and mosques, killing at least three Palestinians and wounding several others, local medics said.
"UN staff remain in Deir al-Balah, and two UN guesthouses have been struck, despite parties having been informed of the locations of UN premises, which are inviolable. These locations - as with all civilian sites - must be protected, regardless of evacuation orders," UN spokesperson Stephane Dujarric said.
To the south in Khan Younis, an Israeli airstrike killed at least five people, including a husband and wife and their two children in a tent, medics said.
In its daily update, Gaza's Health Ministry said at least 130 Palestinians had been killed and more than 1,000 wounded by Israeli gunfire and military strikes across the territory in the past 24 hours, one of the highest such totals in recent weeks.
There was no immediate Israeli comment on the Deir al-Balah and Khan Younis incidents.
Israeli sources have said the reason the army had stayed out of the Deir al-Balah districts was because they suspected Hamas might be holding hostages there. At least 20 of the remaining 50 hostages in captivity in Gaza are believed to be still alive.
Families of the hostages have expressed concern for their relatives and demanded an explanation from Israeli Prime Minister Benjamin Netanyahu, Defence Minister Israel Katz, and the army chief on how they will protect them.
"The people of Israel will not forgive anyone who knowingly endangered the hostages - both the living and the deceased. No one will be able to claim they didn't know what was at stake," the Hostage Families Forum Headquarters said in a statement.
Gaza health officials have warned of potential "mass deaths" in coming days from hunger, which has killed at least 19 people since Saturday, the Hamas-run territory's Health Ministry said.
United Nations Secretary-General Antonio Guterres was appalled by an accelerating breakdown of humanitarian conditions in Gaza "where the last lifelines keeping people alive are collapsing," Dujarric said.
"He deplores the growing reports of children and adults suffering from malnutrition," said Dujarric.
"Israel has the obligation to allow and facilitate by all the means at its disposal the humanitarian relief provided by the United Nations and by other humanitarian organizations."
Health officials say hospitals have been running out of fuel, food aid, and medicine, risking a halt to vital operations.
Health Ministry spokesperson Khalil Al-Deqran said medical staff have been depending on one meal a day and that hundreds of people flock to hospitals every day, suffering from fatigue and exhaustion.
