Iranian Foreign Minister Abbas Araghchi held separate telephone calls with senior officials in Pakistan, Turkey and Saudi Arabia as tensions with the United States escalated.
The calls included Pakistan’s army chief Asim Munir, Turkish Foreign Minister Hakan Fidan and Saudi Foreign Minister Prince Faisal bin Farhan.
Iran said it was prepared to respond firmly to any attack on its sovereignty or national security.
Araghchi said Iran would give a decisive and severe response to any aggression.
He told Saudi Arabia’s foreign minister that Iran would respond in kind to attacks by the United States or Israel, or to regional participation in such action.
A media outlet associated with Iran’s top security establishment said Iran would target oil fields in Saudi Arabia and the United Arab Emirates, and gas fields in Qatar and Israel, if the United States attacked Iranian energy infrastructure.
Iran’s Foreign Ministry alleged that the United States had violated a ceasefire through maritime measures in the Strait of Hormuz, sanctions, a naval blockade and renewed airstrikes.
Trump said he had cancelled planned military action against Iran, provided that an agreement could be reached quickly.
Trump said the proposed agreement would require the Strait of Hormuz to remain fully open to all traffic and what he described as a permanent end to Iran’s nuclear threat.
Trump said several Middle Eastern states and Iran had urged Washington not to proceed because a framework for a possible deal had emerged.
Trump had said a day earlier that he believed U.S. negotiators could still reach an agreement with Iran, while adding that his confidence in Tehran was declining and that further action remained possible if necessary.
Kuwait’s military said it had downed an Iranian drone and alleged that Iranian drones had targeted several important facilities; Iran’s response to that claim was not included in the evidence.
