Iranian Supreme Leader Ali Khamenei expresses his support for negotiations and efforts to revive the 2015 nuclear deal. He also says that the Iranian economy should not be tied to efforts to ease U.S. sanctions against the country.
Saudi foreign minister Faisal bin Farhan Al Saud says that he "sees an emboldened Iran acting in a negative manner around the Middle East, endangering shipping, arming the Houthis and contributing to a political deadlock in Lebanon". Al Saud further stated that Saudi Arabia supports any talks with Iran "as long as it ensures that Iran will not now nor ever get nuclear weapons".
Saudi Arabia intercepts a ballistic missile attack over its capital Riyadh and bomb-laden drones targeting the southern province of Jizan, both of which were launched by Yemen's Houthi rebels backed by Iran.
The United States Secretary of State Mike Pompeo declares the 2015 nuclear accord with Iran as no longer in force. He also warns that the United States "is prepared to use our domestic authorities to impose consequences" for other countries that do not enforce the sanctions. Britain, France, Germany, China, and Russia oppose the snapback sanctions.
