In a joint statement, Israeli Prime Minister Benjamin Netanyahu and Defense Minister Israel Katz said Sunday that the IDF is striking in southern Lebanon.

"As part of Operation Closing Verse, the IDF has now destroyed the underground terror infrastructure of the Hezbollah terrorist organization in the area of the village of Majdal Zun in southern Lebanon," Netanyahu said in the statement, which was also posted to his office's official X account.

"The tunnel, which is over 200 meters long and more than 25 meters deep, contained hundreds of weapons and several launch silos intended to strike the territory of the State of Israel and its citizens. Israel informed the United States and the American representative in Lebanon in advance of the destruction of the infrastructure," the post further said.

"IDF commanders and fighters will remain in the security zone in southern Lebanon and will continue to destroy terrorist infrastructure, remove threats from northern communities, and maintain the security of Israeli citizens," the post concluded.

Kuwait and Bahrain came under attack from "hostile" Iranian missiles and drones early on Sunday, the two countries said following fresh U.S. strikes against Iran.

"Kuwaiti air defenses are currently responding to hostile missile and drone attacks," Kuwait’s army wrote on social media. "Everyone is urged to adhere to the safety and security instructions issued by the relevant authorities."

It provided no further details on the location of the attacks or any damage caused.

The country's Ministry of Foreign Affairs issued a statement expressing its "condemnation and strongest denunciation of the repeated heinous Iranian aggressions against the State of Kuwait" and called the attack a "flagrant violation of its sovereignty."

In Bahrain, the Defence Force said its air defence systems had intercepted and destroyed a number of Iranian missile and drone attacks targeting civilians in the kingdom.

Air-raid sirens went off twice according to the interior ministry, calling on residents to "remain calm and head to the nearest safe place."

Bahrain’s Foreign Ministry issued a statement later condemning what it called "a dangerous escalation that reveals that what Tehran is doing is not a passing act, nor an isolated incident, but rather a deliberate approach and a systematic pattern of repeated aggression against the sovereignty of the kingdom, and the security of its citizens and residents."
