Four people were killed when an Israeli missile hit the home of the Shurafa family in eastern Gaza City, civil defence spokesman Mahmud Bassal told AFP.

Three people were killed and several wounded when a tent housing Palestinians displaced by the war was hit by an Israeli missile in the east of Khan Yunis city, Bassal said.

Another tent housing displaced people in Deir el-Balah in central Gaza was also hit by an Israeli air strike overnight, killing at least four people, he added.

Two other people were killed in separate incidents, Bassal said.

The Israeli military, meanwhile, said its forces were continuing their land and air assault in northern Gaza, where the civil defence says hundreds have been killed since October 6, when the military launched the offensive.

"Over the past day, IDF (military) troops in the area of Jabalia eliminated dozens of terrorists during close-quarters encounters and aerial strikes," the military said in a statement.

Several militants were also killed in central Gaza and in the area of Rafa in the south of the territory, the military added.

Israel has been waging a month-long military offensive in northern Gaza, which it says is aimed at preventing Hamas militants from regrouping.
