However, Trump says an Iran agreement could be signed as soon as this weekend.
President Donald Trump announced "major combat operations" against Iran on Feb. 28, with massive joint U.S.-Israeli strikes targeting military, government and infrastructure sites.
Following the announcement of a two-week ceasefire, initial U.S.-Iran talks in Pakistan in April failed to reach a peace deal.
Trump later announced the open-ended extension of the ceasefire and the continuation of a U.S. blockade until negotiations are concluded "one way or the other."
A U.S. official told ABC News on Thursday that initial assessments indicated that the U.S. intercepted nearly all missiles and drones launched by Iran on Wednesday night. The assessments are ongoing, the official said.
There have been no reports of harm to any U.S. personnel or major damage at U.S. bases, the official said.

The Persian Gulf Strait Authority (PGSA) -- a newly created Iranian entity set up to manage shipping in the Strait of Hormuz and charge fees for vessels transiting the waterway -- said in a post on X on Friday that the Strait would be closed "until further notice."
The PGSA's announcement comes after U.S. Central Command denied reports of the Strait's closure overnight.
The PGSA cited "tensions caused by the aggressive U.S. forces" and an announcement by the Iranian armed forces for the decision to close the waterway. It asked "applicants who have obtained transit permits to remain patient and await further notice."

According to the statement published by the official Islamic Republic News Agency, the ministry warned that the U.S. administration would bear responsibility for the "extremely dangerous consequences" resulting from any escalation.
