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

The Iranian-run Persian Gulf Strait Authority warned against any vessel passing through routes outside its framework after reports of an Iranian drone striking a vessel in the Strait of Hormuz.

"Any passage through routes outside the framework designated by PGSA will not be covered by safe passage guarantees and will not be entitled to insurance coverage or related liabilities," PGSA said in a statement Thursday.

"The consequences arising from passage through unauthorized routes shall be the responsibility of the owner, operator, and vessel commander," PGSA said.

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.
