Iran is open to indirect talks with the US through Oman, but warns regional countries hosting US bases that they could be in the firing line if involved, according to a senior Iranian official. The official stated that indirect talks offer a chance to evaluate Washington's seriousness about a political solution with Iran. Iran has issued notices to Iraq, Kuwait, the UAE, Qatar, Turkey, and Bahrain that any support for a US attack on Iran would be considered an act of hostility. The risk of expanded warfare in the oil-exporting region has unsettled states around the Gulf.
