Also Sunday, Israeli warplanes struck targets in Lebanon following a Hezbollah missile attack that killed two Israeli civilians — an older woman and her adult son — in northern Israel. Opposing demonstrations either demanded the release of Israeli hostages held by Hamas or called for a ceasefire in Gaza. Late Sunday, the Israeli military said it had struck Lebanon in response to the missile strike. Meanwhile, the Egyptian TV station Al-Ghad said a cameraman was killed in an Israeli airstrike in northern Gaza. Details were not immediately available, and the Israeli military had no comment.
