Palestinian officials say Israel’s strikes early Tuesday killed at least seven people in Gaza’s southern city of Khan Younis. They said at least 15 others, including women and children, were injured in the strikes. Israel’s military says it will do “whatever is necessary” to push Hezbollah away from Lebanon’s border with Israel. Israel and Hezbollah have been trading fire since the Israel-Hamas war began. On Monday, Israel launched hundreds of airstrikes in southern and eastern Lebanon, killing nearly 500 people and wounding more than 1,600 others. Thousands of people fled southern Lebanon, jamming the main highway to Beirut in the biggest exodus since the 2006 Israel-Hezbollah war.
