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 hit their home in Beit Hanoun. In separate incidents, a militant and a farmer were killed. The children were aged between one and six years old, the medics said. On Sunday in nearby Beit Lahiya Israeli raids left a 14-year-old girl dead and eight others injured.
