Israel has sent tanks into the central Gazan city of Deir Al-Balah for the first time, where thousands of displaced people are sheltering and some of the remaining hostages are reportedly being held.

At least three Palestinians have been killed and several more wounded after tank shelling hit eight houses and three mosques in the area, medics told Reuters news agency.

A further five people – reported to include parents and their two children who were living in a tent – were killed in an Israeli air strike in Khan Younis in southern Gaza on Monday morning.

Israeli sources said that the military had so far avoided Deir Al-Balah because it believes that Hamas may be holding hostages there. At least 20 of the 50 remaining hostages in Gaza are believed to be alive.

Health clinics and kitchens forced to close

British charity Medical Aid for Palestinians (MAP) said it was forced to suspend many of its operations after the Israeli military ordered residents to evacuate the Deir al-Balah area on Sunday.

Nine clinics, five shelters and a community kitchen have closed, MAP said, adding that the forced displacement orders did not allow for the transport of lifesaving medical equipment or supplies, “thereby further obstructing efforts to provide emergency assistance”.

Shelling was ongoing around their office in Deir al-Balah on Monday morning, and locals were unsure of where to go next, the charity said.

Key infrastructure, including a major water desalination plant that provides clean water to people driven from their homes, also falls within the forced displacement orders and “remains at high risk”, a spokesperson for the charity said.

Newborn babies were starving to death because mothers were too malnourished to produce breastmilk, and there was no longer enough baby formula in Gaza, interim CEO Steve Cutts said.

Health officials in Gaza warned of a growing risk of “mass death” from starvation, as aid deliveries into Gaza remain limited by Israel.

At least 19 people – including children – have died from hunger in the last 24 hours alone, according to Dr Khalil Al-Deqran, spokesperson for the Hamas-run health ministry.

“Hospitals can no longer provide food for patients or staff, many of whom are physically unable to continue working due to extreme hunger,” he said.

“Hospitals cannot provide a single bottle of milk to children suffering from hunger, because all baby formula has run out from the market.”

At least 93 people were killed by Israeli gunfire while waiting for aid at the northern Zimkim crossing on Sunday, Gaza’s civil defence agency said, the latest in a string of killings at aid sites.

The Israeli military said it had fired warning shots into a crowd in northern Gaza to remove an “immediate threat”, and claimed that casualty figures were inflated.

Nine others were reportedly shot dead near an aid point close to Rafah in the south, a civil defence spokesperson said.
