Palestinian medics say Israeli airstrikes have killed at least five people in the Gaza Strip, including two infants and a woman.

At least 19 Palestinians, including eight children, were killed in Israeli air strikes in southern Gaza overnight, local health officials say. A mother and her four children were reportedly killed when a tent camp for displaced people in al-Mawasi was hit, while another a couple and their children died in the nearby city of Khan Younis.
