An Israeli airstrike in Gaza has killed 10 people and flattened a three-storey home, bringing the total death toll from strikes in the past 24 hours to at least 49. Israel's military claims to have targeted a Hamas militant, but a local resident disputes this. Israel has vowed to continue the war until all hostages are returned and Hamas is destroyed or disarmed. Meanwhile, aid groups warn that supplies in Gaza are dwindling, with the World Food Programme announcing that its food stocks have run out.
