Iran, which denies seeking to develop a nuclear weapon, has insisted it will not give up domestic uranium enrichment despite the bombings of three nuclear sites. Trump told reporters that Iran has been sending out "nasty signals" and any effort to restart its nuclear program will be immediately quashed.

Trump issued the threat as he held talks with British Prime Minister Keir Starmer at his Turnberry golf resort on the western coast of Scotland.

President Trump has again threatened Iran over its nuclear program, warning of military action if uranium enrichment continues. Iran responded firmly, saying it won't yield to threats and maintains its right to enrich for peaceful purposes.
