Iran live updates: US and Iran agree to stop strikes, US official says

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.

The Israeli military says its troops killed a Hezbollah militant that it said was responsible for the death of an Israeli soldier in Deir Siryan, southern Lebanon, overnight.

"IDF soldiers from the Golani Brigade Combat Team encountered a Hezbollah terrorist after entering a suspicious structure in the area of Deir Siryan in southern Lebanon. As a result of the encounter, Captain David Hazutt fell, and an additional IDF soldier was lightly injured," the IDF statement said.

"Following extensive searches conducted by IDF soldiers in the area, the terrorist was located in one of the structures near the point of the encounter and was eliminated by the soldiers," the statement continued, adding that the IDF "will continue to operate to remove any threat posed to IDF soldiers and will not allow the Hezbollah terrorist organization to harm Israeli civilians and IDF soldiers."

Iran's foreign minister, Abbas Araghchi, said on Sunday that only Iran is responsible for reopening the Strait of Hormuz and restoring shipping traffic to pre-war levels.

"These arrangements are being adopted and implemented, and responsibility for them rests with the Islamic Republic of Iran," Araghchi said during a news conference alongside his Iraqi counterpart on Sunday. "No other body or country bears any responsibility in this regard."

The minister's comments followed U.S. strikes on Iranian targets, which came after officials in Washington accused Tehran of targeting a tanker in the strait. Both the United States and Iran have claimed in recent weeks to have control over the strait.

Araghchi added on Sunday that attempts "to adopt new or separate arrangements" would "only complicate the situation, delay the reopening of the Strait of Hormuz and raise the level of tension, as we witnessed over the past two nights with incidents in the Strait of Hormuz that led to increased tensions and clashes."

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."
