Palestinian officials say an Israeli strike hit a tent sheltering a displaced family in the central Gaza Strip, killing at least three people including the parents of twins.

The strike hit a house in the city of Jabaliya, which has repeatedly come under attack as the Israeli military has pressed an offensive in northern Gaza.

Dozens of people have been killed and wounded in an Israeli strike on a house in Jabalia in northern Gaza, Palestinian medics and rescuers say. The official Palestinian news agency Wafa and Gaza's Hamas-run civil defence agency said at least 30 people had been killed.
