Iran and the United States said they made progress in negotiations over Iran's nuclear program in Rome and that their senior negotiators would meet again in Oman following technical-level discussions. The talks in Rome were the second round of negotiations mediated by Oman that began earlier in April. Iranian foreign minister Abbas Araqchi met with Russian president Vladimir Putin in Moscow before the Rome talks, while U.S. special envoy Steve Witkoff met with Israeli officials and the director of the International Atomic Energy Agency (IAEA). Two days prior to the talks, two Airbus A330-200 aircraft sought by Iranian national airline Iran Air arrived in Tehran. Delivery of the aircraft would have required approval from the U.S. Treasury Department due to U.S. sanctions on Iran.
