Iran live updates: US and Iran trade strikes as Israel hits Beirut

The U.S. carried out new airstrikes in southern Iran, shooting down four one-way attack drones that posed a threat around the Strait of Hormuz and then a ground control site, a U.S. official said.

The official said U.S. forces struck an Iranian ground control station in Bandar Abbas that was about to launch a fifth drone.

The official called the strikes "measured, purely defensive, and intended to maintain the ceasefire."

This is the second time in three days that the U.S. has carried out self-defense strikes against Iranian military targets in southern Iran. 

On Monday the U.S. carried out airstrikes against Iranian missile locations and boats that U.S. Central Command said were preparing to launch mines in the Strait of Hormuz.

Speaking at a cabinet meeting on Wednesday, President Donald Trump said the Iranians "want very much to make a deal," but an agreement hasn't been reached yet.

"We're not satisfied with it, but that we will be. Either that or we'll have to just finish the job," Trump said.

"Iran cannot have a nuclear weapon. I'm doing that for the world. I'm not doing it just for us," Trump said.

The White House addressed reports on an initial memorandum of understanding between the U.S. and Iran on Wednesday, saying that negotiations are "proceeding nicely" and that the president would only make a deal "which must ensure that Iran can never have a nuclear weapon."

“As President Trump has said, negotiations are proceeding nicely and he has made his redlines clear. President Trump will only make a good deal for the American people, which must ensure that Iran can never have a nuclear weapon," White House spokesperson Olivia Wales said in a statement when asked about the reports.

Iranian State TV has released details of what it said is in a possible Memorandum of Understanding between Iran and U.S., but aknowledged the agreement has not yet been finalized.

As part of the agreement, U.S. military forces will withdraw from the surrounding environment of Iran, and the naval blockade of Iran will be lifted, Iranian State TV said.

The White House Rapid Response account railed against the reports of an initial memorandum of understanding between the U.S. and Iran, claiming it to be "not true" and a "complete fabrication."

"This report from Iranian controlled media is not true and the MOU they 'released' is a complete fabrication. Nobody should believe what Iranian state media is putting out. FACTS MATTER," the Rapid Response X account said, in response to a Fox News broadcast detailing the report of the alleged document.
