Israel has killed many of Hezbollah's senior leaders with devastating strikes in Lebanon, but neither side appears ready to step back from the brink.

Israel's defence minister Yoav Gallant tells troops in the north they are prepared to use forces "from the air, sea, and land".

The televised statement by the deputy leader, Sheikh Naim Qassem, was the first public address by a senior Hezbollah figure since Israel’s killing of the group’s longtime chief, Hassan Nasrallah.
