Iran’s supreme leader on Tuesday pushed back against US criticism of the country’s nuclear program, saying that Tehran won’t seek permission from anyone to enrich uranium and calling American statements “nonsense.”

“They say, ‘We won’t allow Iran to enrich uranium.’ That’s way out of line,” Ayatollah Ali Khamenei said during a memorial for late President Ebrahim Raisi, who died in a helicopter crash last year, AP reports.

“No one in Iran is waiting for their permission. The Islamic Republic has its own policies and direction — and it will stick to them.”

Khamenei’s remarks came as indirect talks between Iran and the US reportedly continue, though he expressed doubt about their outcome.

“Yes, indirect negotiations were held during Raisi’s time too, just like now,” he said. “But they didn’t go anywhere — and we don’t expect much from the current ones either. Who knows what will happen.”

His comments reflect Tehran’s growing frustration with the stalled nuclear discussions, as well as the broader tensions that have defined US-Iran relations in recent years.

Foreign Ministry spokesman Esmaeil Baghaei told the state-run IRNA news agency that “no definitive decision has been made about the next round of negotiations,” adding that “the Islamic Republic of Iran is reviewing the matter while considering the US side’s contradictory and constantly changing positions.”

IRNA also reported that Kazem Gharibabadi, the deputy foreign minister, said that Tehran had received a proposal regarding the next round of indirect talks with Washington and was currently reviewing it.
