At least nine people, including five children, have been killed in an Israeli strike while fetching water in al-Mawasi, an area of southern Gaza which Israel has designated as a safe zone, health officials said.

A doctor from al-Nasser hospital shared a picture of the children’s bodies in the hospital, as well as a picture of water jugs left in a pool of blood at the site of the attack on Tuesday.

The attack came shortly after the Israel Defense Forces encouraged people to leave Gaza City for al-Mawasi, before Israel’s looming invasion of Gaza City. “We wish to remind you that in al-Mawasi, enhanced services will be provided with an emphasis on access to medical care, water and food,” the Israeli military’s Arabic-language spokesperson Avichay Adraee said in a post on X on Tuesday afternoon.
