The US and Iran have agreed to hold nuclear talks in Oman on Friday, as President Donald Trump issued a blunt warning to Supreme Leader Ayatollah Ali Khamenei. Iranian Foreign Minister Abbas Araghchi confirmed that the meeting would start at 10:00 (06:00 GMT) in Muscat. Trump's administration has ramped up military presence in the region and has threatened action if Iran fails to comply with demands regarding its nuclear program. The negotiations had appeared uncertain earlier due to disagreements over logistics and conditions. Key factors in the discussions include Iran's ballistic missile production, support for regional militias, and the ongoing domestic unrest in Iran, which has resulted in significant casualties due to government crackdowns. Iranian authorities maintain the peaceful intent of their nuclear program amid an atmosphere of tension where both nations are on high alert.
