Air raid sirens echoed across Tel Aviv as a missile exploded over the hotel where US Secretary of State Antony Blinken was staying.
Both sides appear to be dug in. Israeli Prime Minister Benjamin Netanyahu has pledged to annihilate Hamas and recover dozens of hostages held by the group.
Hamas says it will only release the captives in return for a lasting cease-fire, a full Israeli withdrawal from Gaza and the release of Palestinian prisoners.
Unlike the bruising monthlong war between Israel and Hezbollah in 2006, in which an Israeli strike almost immediately took Lebanon’s only commercial airport out of commission, it has not been targeted in the current conflict.
