Israeli military strikes killed at least 23 Palestinians across the Gaza Strip on Sunday, including a local journalist and a senior rescue service official, local health authorities said.

The latest deaths in the Israeli campaign resulted from separate Israeli strikes in Khan Younis in the south, Jabalia in the north and Nuseirat in the central Gaza Strip, medics said.

In Jabalia, they said local journalist Hassan Majdi Abu Warda and several family members were killed by an airstrike that hit his house earlier on Sunday.

Another airstrike in Nuseirat killed Ashraf Abu Nar, a senior official in the territory's civil emergency service, and his wife in their house, medics added.

There was no immediate comment by the Israeli military.

The Hamas-run Gaza government media office said that Abu Warda's death raised the number of Palestinian journalists killed in Gaza since October 7, 2023, to 220.

In a separate statement, the media office said Israeli forces were in control of 77% of the Gaza Strip, either through ground forces or evacuation orders and bombardment that keeps residents away from their homes.

The armed wing of Hamas and the Islamic Jihad said in separate statements on Sunday that fighters carried out several ambushes and attacks using bombs and anti-tank rockets against Israeli forces operating in several areas across Gaza.

On Friday the Israeli military said it had conducted more strikes in Gaza overnight, hitting 75 targets including weapons storage facilities and rocket launchers.

Israel launched an air and ground war in Gaza after Hamas militants' cross-border attack on October 7, 2023, which killed 1,200 people by Israeli tallies with 251 hostages abducted into Gaza.

The conflict has killed more than 53,900 Palestinians, according to Gaza health authorities, and devastated the coastal strip. Aid groups say signs of severe malnutrition are widespread.
