Lebanese militant group Hezbollah condemned Wednesday Israel's killing of Iranian national security chief Ali Larijani, calling it "cowardly".

"We in Hezbollah, as we condemn this cowardly assassination and the ongoing criminal American–Israeli aggression, affirm that the assassination of leaders will neither break the will of the Islamic Republic nor undermine the determination of its leadership, its people, and its fighters," the Iran-backed group said.

The European Union has called on Israel to cease its military campaign in Lebanon, after the latest Israeli strikes on Beirut.

"The EU is deeply concerned about the ongoing Israeli offensive in Lebanon which already has devastating humanitarian consequences and risks triggering a prolonged conflict," a spokesperson said in a statement Wednesday.

Kuwait arrested 10 militants affiliated with the Iran-backed Lebanese Hezbollah group on Wednesday, who were accused of plotting "terrorist" actions against vital infrastructure, the interior ministry said.

This was the second Hezbollah-affiliated cell to be arrested in Kuwait this week, as the Gulf faced daily Iranian attacks during the Middle East war, which has seen Tehran-backed groups including Hezbollah join the conflict.

A pro-Iran group in Iraq vowed Thursday to stop attacking the U.S. embassy in Baghdad for five days, but only under certain conditions, with strikes targeting other locations in the country.

After a wave of strikes on the U.S. embassy in Iraq's capital Baghdad in recent days, AFP journalists reported no drone or rocket attacks on Wednesday night.

Air raid sirens rang out late Wednesday across Israel from the north to the south following what Israeli media said was one or more missile launches from Lebanon.

The Israeli military did not immediately comment on a report from the N12 television channel that a missile fired from Lebanon had been intercepted over the southern coastal city of Ashdod.

France's foreign minister will visit Lebanon on Thursday, the ministry told AFP, after the EU called on Israel to stop its military strikes on the country.

Israel's defense minister said the Israeli military had destroyed two bridges spanning the Litani River in southern Lebanon on Wednesday, alleging they were being used by Hezbollah.

The line of cars stretched as far as the eye could see along the coast of southern Lebanon, as residents of areas bombarded in the Israel-Hezbollah war poured into the ancient city of Sidon in search of safety.

U.S. President Donald Trump angrily suggested Wednesday that he could leave U.S. allies to secure the Hormuz strait on their own since they have refused to fight alongside U.S. forces against Iran in the crucial shipping lane.

Saying the United States doesn't need the strait -- a major global oil shipping pathway -- Trump wrote on his Truth Social site that he could "let the Countries that use it" find a solution.
