At least 11 Palestinians were killed in Israeli air strikes in the northern and southern Gaza Strip on Sunday, Palestinian civil defence and health officials said.

Medics said an Israeli air strike on a tent encampment housing displaced families killed at least four civilians, while health officials said another strike killed five in Khan Younis in the south.

An Israeli military official claimed that Israel Defence Forces were striking “terrorists” in response to “a violation (on Saturday) in Beit Hanoun where terrorists emerged from a tunnel east of the yellow line”.

The official called Sunday’s strikes “precise” and alleged Hamas had committed more than six violations of an October ceasefire, including deploying east of the “Yellow Line” agreed under the ceasefire to demarcate Israeli- and Hamas-controlled areas.

Israel and Hamas have repeatedly accused each other of violating the ceasefire deal, a key element of US President Donald Trump’s plan to end the Gaza war.

On Saturday, the military claimed it had identified armed “terrorists” near the occupying Israeli army operating in the northern Gaza Strip.

The occupation army claimed it destroyed underground tunnels in the northern Gaza Strip in accordance with the agreement.

It alleged it observed several gunmen emerging from what it said was a tunnel and entering beneath the rubble of a building east of the Yellow Line.

The occupation military said air force aircraft had attacked the building and eliminated two people, and that it was likely that additional people were eliminated in the strike.

The Gaza health ministry said at least 600 Palestinians have been killed by Israeli fire since the Gaza deal began.
