BEIRUT (AP) — Israel’s military issued warnings to residents of dozens of border villages in southern Lebanon to evacuate “immediately” Wednesday as airstrikes on suburbs of Beirut intensified and Hezbollah claimed more attacks.

An American submarine sank an Iranian warship and Iran threatened the destruction of military and economic infrastructure across the region.

Israel announced multiple incoming attacks early Thursday and said it was intercepting the missiles. The Israeli military says it began new strikes in Lebanon against the Iranian-backed Hezbollah militant group.

Air strikes rock Lebanese capital while Hezbollah launches missiles and drones into Israel, opening a dangerous new front amid fallout from US-Israel attacks on Iran.

The US, Israel-Iran war has widened sharply, with a US submarine sinking an Iranian warship off Sri Lanka on Wednesday, killing at least 80 people, and NATO air defences destroying an Iranian ballistic missile fired towards Turkey.

Israel continued waves of heavy airstrikes in Beirut after Hezbollah began firing on Israel in support of Iran. Nearly 85,000 people have been displaced, according to the Lebanese government. The Israeli military has also started a ground incursion into southern Lebanon,
