JERUSALEM — Hezbollah fired into a disputed border zone held by Israel on Monday after multiple Israeli strikes inside Lebanon since a cease-fire took hold last week. The militant group said the volley, its first during the truce, was a warning shot in response to what it called repeated Israeli violations.

The Israel Defense Forces continued its intense airstrike and ground campaigns in Gaza -- particularly in the north of the strip -- and in Lebanon, with Israeli attacks on targets nationwide including in the capital Beirut.
