Iran live updates: US forces conduct strikes on Iranian targets over Strait of Hormuz drone attack

A U.S. official confirmed to ABC News that Iran attacked a ship in the Strait of Hormuz with a drone.

The International Maritime Organization announced it temporarily suspended the evacuation of vessels from the Strait of Hormuz after reports of an attack on a vessel in the Gulf of Oman.

"This vessel did not transit under IMO’s evacuation framework. I have always reiterated that the safety of the seafarers remains paramount. Therefore, to ensure a coordinated approach and navigational safety, the evacuation plan will be paused until further clarity is obtained," IMO Secretary-General Arsenio Dominguez said in a statement Thursday.

An $87.6 billion supplemental budget request to Congress from the Trump administration includes $67.1 billion for the Pentagon, partly to cover the costs incurred during the Iran war.

It includes:

$1.5 billion for fuel -- oil and gas prices surged during the war, which has strained the Pentagon's budget.

$21 billion for munitions costs -- it’s unclear whether this will be used to replace missiles and bombs used against Iran or includes additional purchases.

$17.3 billion for "operational costs" and another $1.7 billion for "readiness," which are generally large umbrella terms that can mean training or other costs associated with the day-to-day running of the services and related to costs incurred during the war by having so many ships, aircraft and personnel deployed in the Middle East for the conflict.

It can also contain funds to make up for shortfalls within the military to include day-to-day costs and training operations.

Costs associated with repairing base infrastructure destroyed by Iran are not covered by the supplemental budget.

Jay Hurst, the Pentagon comptroller, told lawmakers last month that given that it's unclear what the long-term Middle East footprint is going to be, there hasn't yet been a notable plan developed to rebuild bases abroad.

The Israel Defense Forces will maintain a security zone in southern Lebanon, Prime Minister Benjamin Netanyahu vowed on Wednesday.

"As long as I am Prime Minister, Iran will not have nuclear weapons. And another thing, as long as I am Prime Minister, we will maintain the security zone in southern Lebanon," Netanyahu said at a municipal government summit in Tel Aviv.

"There is more work to be done, in Gaza, in Lebanon, and against Iran too," Netanyahu continued.

In the lengthy remarks, Netanyahu touted his government's achievements against Iran, Hezbollah in Lebanon and Hamas in Gaza

"Iran would already have had an atomic bomb to destroy us, and we have averted that. We have averted the immediate threat of thousands of ballistic missiles," Netanyahu said.

In earlier remarks at the summit, Israeli Defense Minister Israel Katz said the U.S. had not asked Israel to withdraw from Lebanon and said that Israel would not withdraw from Lebanon even if the U.S. demanded it.

"We've made it clear, the Prime Minister to the President, me to Hegseth the minister of war -- the IDF, we are there to protect the residents of the north," Katz said when asked if Israel would withdraw from Lebanon if the U.S. demanded it.
