U.S. President Donald Trump made sweeping new demands on Iran after Tehran reiterated requests for reparations as part of talks to wind down the conflict, dimming hopes of a quick deal that would reopen the vital Strait of Hormuz as oil prices surged once again.

“I am likewise demanding compensation from Iran, for all of the people that they have killed and gravely wounded with their roadside bombs and many conflicts,” Trump wrote on social media. “Additionally, compensation should be paid to the families of the hundreds of thousands of innocent protestors that Iran has killed over the last 50 years.”

The new demands from Trump, which he said will be put “firmly into any, and all, future negotiations,” are almost certain to be rejected by Iran, and come after Tehran stressed it was seeking compensation for the U.S. and Israeli war launched on Feb. 28. Shortly after his post, Trump expanded the scope of his demands, saying Iran should be responsible for “damages and death to the people of Lebanon, Syria, Yemen, and Gaza,” without offering any details.
