The United States has bombed three nuclear sites in Iran, President Donald Trump announced in a post on Truth Social on Saturday, as the Israel-Iran conflict entered the second week.

Trump will address the nation at 10 p.m. Eastern Time. He said it is "time for peace now".

The bombed nuclear sites include Fordow, Natanz, and Esfahan.

"We have completed our very successful attack on the three Nuclear sites in Iran, including Fordow, Natanz, and Esfahan. All planes are now outside of Iran air space. A full payload of BOMBS was dropped on the primary site, Fordow. All planes are safely on their way home. Congratulations to our great American Warriors. There is not another military in the World that could have done this. NOW IS THE TIME FOR PEACE! Thank you for your attention to this matter," Trump wrote in the post.

In another post, he said the military operation was successful and congratulated 'American warriors'.

The conflict started a week ago when Israel launched airstrikes against Iranian nuclear and military sites, primarily targeting uranium enrichment facilities to prevent Iran from developing nuclear weapons.

The two countries have been engaged in aerial strikes simce then.

Earlier, Trump had said he was weighing in on the situation of whether to join the conflict.

According to reports, B-2 bombers took off from Whiteman Air Force Base in Missouri in the early morning hours of Saturday (US time).

The warplanes are known not only for their stealth technology, but also for their ability to fly long-range and carry the big “bunker buster” bombs used in the June 21 mission.
