On the eve of renewed nuclear negotiations between Washington and Tehran, Iran has issued a stern warning, holding the United States accountable for any potential Israeli strikes on its nuclear facilities.
The warning follows a CNN report, which cited unnamed U.S. officials claiming that Israel is preparing to target Iranian nuclear sites, despite ongoing diplomatic efforts.
In a letter to the United Nations released Thursday, Iranian Foreign Minister Abbas Araghchi stated, “We believe that in the event of any attack on the nuclear facilities of the Islamic Republic of Iran by the Zionist regime, the U.S. government will also be involved and bear legal responsibility.”
Araghchi further cautioned, “Iran strongly warns against any adventurism by the Zionist regime and will respond decisively to any threat or unlawful act by this regime.”
These remarks come as high-level nuclear talks—resumed on April 12—are set to continue with a fifth round in Rome on Friday. The negotiations mark the most significant dialogue between the two adversaries since the U.S. withdrew from the 2015 nuclear agreement during Donald Trump’s presidency.
Oman, acting as mediator, confirmed the location of the next round of discussions. The U.S. delegation is expected to include Steve Witkoff, a close ally of Trump, and Michael Anton, a senior policy planner at the State Department involved in technical aspects of the negotiations.
A central challenge in the talks remains uranium enrichment. The 2015 agreement, brokered under former President Barack Obama, allowed Iran to enrich uranium only to low levels for civilian energy use. However, Iran is currently enriching uranium to 60%—significantly above the 3.67% limit set in the deal, but still below the 90% required for weapons-grade material.
