At least seven Palestinians, including a mother and her four young children, have been killed during an Israeli raid in northern Gaza, medics say.

The family members were killed when a missile or shell hit their home in Beit Hanoun, witnesses and Palestinian officials said.

The Israeli military said it had hit gunmen carrying explosives which had detonated, causing the deaths.

The children were aged between one and six years old, medics said.

In separate incidents, a militant and a farmer were killed.

The area is often used by Palestinian militants to launch rockets at Israel.

Clashes between Israeli ground forces and Palestinian militants on Sunday in nearby Beit Lahiya left a 14-year-old girl dead and eight others injured.
