President Trump has sent a revised set of stricter terms to Iran as part of a proposed peace framework, according to administration officials.
The changes to the deal were potentially designed to speed up negotiations by increasing pressure on Iran to accept the current structure, one official said.
Officials did not specify all the new conditions but indicated they address key sticking points in the ongoing talks.
The revised framework follows months of indirect negotiations between the United States and Iran.
Iranian officials have not publicly responded to the updated terms, but analysts expect a careful review.
The Trump administration has maintained a policy of maximum pressure on Iran, including economic sanctions.
If accepted, the framework could pave the way for a broader agreement on nuclear and regional issues.
Diplomats have warned that the tougher terms may risk derailing progress made in earlier rounds of discussion.
The White House has not confirmed the exact timeline for Iran’s formal response to the new proposals.
