Yemen missile
Israel's ongoing bombardments in Lebanon have raised fears of an all-out regional war in the Middle East.
Israel said earlier this month that it was shifting its focus from the Gaza Strip, where it has been fighting a war with Hamas since the October 7 attack, to its border with Lebanon.
Israel's military chief, Lieutenant General Herzi Halevi, has told soldiers to prepare for a possible ground offensive, according to an army statement.
The Israeli military said Thursday it intercepted a missile fired from Yemen.
The leader of Yemen's Huthi rebels, Abdul Malik al-Huthi, said in a televised address earlier Thursday that the Iran-backed group would "not hesitate to support Lebanon and Hezbollah".
Since November, the Huthis have targeted Red Sea shipping with drones and missiles, saying the actions are in solidarity with Palestinians in the Gaza war, which was sparked by Hamas's October 7 attack on Israel.
Gaza key
Diplomats have said efforts to end the war in Gaza were key to halting the fighting in Lebanon.
But despite months of mediation efforts involving the United States, a Gaza ceasefire is as elusive as ever.
At the UN General Assembly in New York, Saudi foreign minister Faisal bin Farhan Al Saud announced a new international coalition to seek a two-state solution in Gaza.
Hamas's October attack resulted in the deaths of 1,205 people, mostly civilians, according to an AFP tally based on Israeli official figures that include hostages killed in captivity.
Of the 251 hostages seized by militants, 97 are still held in Gaza, including 33 the Israeli military says are dead.
Israel's retaliatory military offensive has killed at least 41,534 people in Gaza, most of them civilians, according to figures provided by the Hamas-run territory's health ministry. The UN has described the figures as reliable.
