Iranian security official Ali Larijani is in Oman, the country currently mediating talks between Tehran and Washington over Iran's nuclear program. Larijani likely discussed recent indirect talks held in Muscat, the Omani capital. He met with Omani Foreign Minister Badr al-Busaidi and Sultan Haitham bin Tariq. The talks have been described as “important,” though details remain unclear. The U.S. has increased its military presence in the Middle East, including sending the aircraft carrier USS Abraham Lincoln, to pressure Iran into an agreement.
