The active phase of negotiations with Iran will continue until the deadline for concluding a deal set by US President Donald Trump, US Vice President JD Vance said.

There are still many negotiations to be held with Iran before that, Vance said at a news conference in Budapest.

Earlier, Trump demanded that Iran’s new authorities take immediate action, threatening to destroy the country's bridges and power plants.

In addition, the US president announced plans to deliver powerful strikes to Iran and send the country back to the "Stone Age."
