The strikes come after the United Nations announced it would reduce its presence in Gaza following an alleged Israeli attack on one of its buildings, killing one employee.
At least 23 people were killed in overnight Israeli strikes on Gaza, Palestinian hospitals reported on Tuesday.
The dead include three children and their parents, who were killed in a strike on their tent near the southern city of Khan Younis, according to Nasser Hospital, which said it received four additional bodies from two other strikes in addition to the family of five.
In central Gaza, the Al-Aqsa Martyrs Hospital said it received the bodies of six people who were killed in three separate strikes. Three others were killed in a strike on a house in the built-up Nuseirat refugee camp, according to the Awda Hospital.
In Gaza City, an Israeli strike on a residential building killed five people, according to the Health Ministry’s emergency service. Another 12 people were wounded, it said. Euronews could not independently verify the casualty reports.
On Monday, two journalists were also killed in Israeli airstrikes, including Hossam Shabbat, who worked for Qatar's Al Jazeera satellite news network.
Israel launched the campaign vowing to destroy Hamas after its 7 October 2023 attack on southern Israel, in which militants killed some 1,200 people and abducted 251. Israel says it only targets militants and blames Hamas for civilian deaths because it operates in densely populated areas.
Israel has also said it restarted its bombardment and cut off food to Gaza to force Hamas to accept new terms for the ceasefire and release more hostages.
Meanwhile, officials say Egypt has introduced a new proposal to try and get the ceasefire back on track.
UN and Red Cross buildings hit by strikes
The United Nations said Monday it will “reduce its footprint” in the Gaza Strip by about 100 staffers after an Israeli tank strike hit one of its compounds, killing one staffer and wounding five others last Wednesday.
In a statement Monday, UN Secretary-General spokesman Stéphane Dujarric said that “based on the information currently available,” the strikes on the site “were caused by an Israeli tank.”
He emphasised that the UN “is not leaving Gaza,” pointing out that it still has about 13,000 national staff in Gaza, mainly working for UNRWA, the UN agency for Palestinian refugees.
Israel has denied it was behind the 19 March explosion at the UN guesthouse in central Gaza.
The move comes as Israel has cut off all food, fuel, medicine and other supplies to Gaza’s around 2 million people for more than three weeks.
Other aid workers have also come under fire in Gaza. The International Committee of the Red Cross said its office in the southern city of Rafah was damaged by a projectile.
It said no staff were hurt, but the damage has a direct impact on its ability to operate. It did not specify who was behind the explosion.
Israel later claimed responsibility but said it fired on the Red Cross building by mistake, adding that troops shot at the building after identifying a threat from Palestinian militants.
“It was later determined that the identification was false,” the Israeli military said in a statement, adding that the incident will be reviewed.
