At least four Palestinians have been killed in Israeli air strikes and gunfire in separate incidents across the Gaza Strip, health officials said on Tuesday.

An Israeli air strike killed Akram Yassin and his wife Dina Abu Baker in an apartment in Gaza City. Medics said the residential flat was targeted without warning.

In Khan Younis, in southern Gaza, a 17-year-old boy was shot and killed by Israeli gunfire near the Qizan an-Najjar neighbourhood. A fourth person was killed by Israeli gunfire in the Zeitoun suburb, east of Gaza City.

The Israeli military also carried out artillery attacks in other areas south of Khan Younis, according to reports.

A correspondent reporting from Deir el-Balah described a surge in Israeli attacks across Gaza overnight and into the early hours of Tuesday, with strikes concentrated on Gaza City.

"We can see that the attacks have been pretty much concentrated on Gaza City, where a residential flat was targeted without any warning," the correspondent said.

"We are seeing very distressing scenes, and footage coming from the site of the attack shows the scale of destruction that has been inflicted upon the whole residential area," he added.

"We also saw a clear activation of Israeli drones and fighter jets through the early hours of this morning across the central areas of the territory."

Palestinians inspected the aftermath of the strike on the apartment in Gaza City before gathering for the couple's funeral.

Mahmoud Yassin, whose brother was among those killed, said the violence had not stopped despite an announced ceasefire. "We're supposed to be in a ceasefire period, but honestly, we are not seeing a ceasefire or anything. The war is still going on, assassinations are continuing, and the shelling has not stopped," he said.

According to Gaza health authorities, the conflict has killed at least 74,480 Palestinians since October 2023, with another 175,539 wounded.

Since a ceasefire announced in October 2025, 1,522 Palestinians have been killed and 5,421 wounded in Israeli attacks, with 839 bodies recovered from under the rubble.

The United Nations reports that approximately 82 percent of structures in Gaza, roughly 200,000 buildings, have been damaged, with about two-thirds of them destroyed since the start of the war.
