At least nine Palestinians were killed in Israeli airstrikes in northern and southern Gaza Strip on Sunday, Palestinian civil defense and health officials said, Reuters reported.

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

An Israeli military official said Israel Defense Forces were striking Hamas "terrorists" in response to "a violation (on Saturday) in Beit Hanoun where terrorists emerged from a tunnel east of the yellow line".
