President Donald Trump warned on Monday that he would order fresh U.S. attacks on Iran’s nuclear facilities should Tehran try to restart facilities that the United States bombed last month.

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.

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 Iran has been sending out “nasty signals” and any effort to restart its nuclear program would be immediately quashed.

“We wiped out their nuclear possibilities. They can start again. If they do, we’ll wipe it out faster than you can wave your finger at it,” Trump said.

Iranian Foreign Minister Abbas Araghchi said on Monday Tehran is fully aware of the impact of what he called the American-Israeli aggression on both sides and warned that any repeat of such actions would prompt a decisive response.

“If aggression is repeated, we will not hesitate to react in a more decisive manner and in a way that will be IMPOSSIBLE to cover up,” Araghchi posted on X, without providing further specifics.

The U.S. launched strikes last month on Iranian nuclear facilities that Washington says were part of a program geared towards developing nuclear weapons. Tehran maintains that its nuclear programme is for purely civilian purposes.
