U.S. military strikes on Iran will intensify next week if Tehran does not cooperate in peace talks in the coming days, U.S. President Donald Trump warned on Tuesday.

Axar.az reports, citing CNBC, in an interview with Fox News on Tuesday evening, Trump hinted that the conflict was more likely to intensify than de-escalate as a fragile ceasefire agreed last month continues to fracture.

"We're going to hit them very hard tonight," he said. "We're going to hit them hard tomorrow night. We're going to hit them really hard the night after."

He added that U.S. forces would go on to target key Iranian infrastructure next week without a diplomatic breakthrough.

"Next week it gets really bad for them because next week comes the power plants," he said. "Next week comes the bridges. We're going to knock out all their power plants. We're going to knock out all their bridges unless they get to the table and negotiate."
