President Trump said Wednesday that the interim agreement with Iran was “over” but he will allow talks to continue.

“For me, I think it’s over,” Trump responded when asked about the status of the ceasefire. Referring to the country’s leadership as “sick,” he added: “It’s just a waste of time dealing with them.”

He made the comment on the sidelines of the two-day NATO summit in Ankara, Turkey, and hours after striking Iran in what the U.S. described as retaliation for attacks on tankers in the Strait of Hormuz.

Oil prices jump 5% after Trump says Iran ceasefire over

World oil prices soared more than five percent Wednesday after President Trump said the ceasefire with Iran was over, following a fresh exchange of strikes in the Middle East.

International benchmark Brent North Sea crude jumped 5.3 percent to $78.09 a barrel, while the main U.S. contract, West Texas Intermediate, advanced 5.4 percent to $74.23 a barrel.

The U.S. said it had hit over 80 Iranian targets overnight following attacks on ships in the Strait of Hormuz, triggering a wave of reprisals against American bases in the Gulf.
