U.S. President Donald Trump has warned that American attacks on Iran’s power plants and bridges will intensify next week if Tehran does not agree to a deal. He issued the threat during an interview with Fox News on Tuesday, saying that the coming week would be “really bad” for Iran if it refuses to return to negotiations. Trump stated that all of Iran’s power plants and bridges would be destroyed if no agreement is reached.

The warning came as U.S. forces continued airstrikes in Iran for a fourth consecutive day and reimposed naval blockades on the country’s seaports. The escalation follows the collapse of a fragile ceasefire reached on June 17, with the main conflict now centered on control of the strategically vital Strait of Hormuz.

When asked how long the attacks would continue, Trump said they would go on “as long as I say it’s enough,” signaling no immediate end to the military campaign.
