US Secretary of State Antony Blinken and Saudi Foreign Minister Prince Faisal bin Farhan Al Saud discussed Iran's nuclear program and its destabilizing activities across the Middle East.

The US Embassy in Saudi Arabia tweeted on Tuesday that Blinken and Prince Faisal bin Farhan discussed the challenge posed by Iran’s nuclear program and its destabilizing behavior in the region, and opportunities for greater cooperation on regional issues.

Blinken also underscored the importance of international support for Ukraine as it defends its sovereignty and territorial integrity, stressing the need for a global response to the food security crisis resulting from the Russian invasion of the country.

Relations between Washington and Riyadh have been relatively cool since President Joe Biden took office because of several policies he adopted, including his decision to revive the 2015 nuclear deal with Iran and less military support for Saudi Arabia. 

On Monday, Blinken condemned the "unjustified seizure" of two Greek-flagged vessels by Iran's Revolutionary Guard, saying "Iran's continued harassment of vessels and interference with navigational rights and freedoms are a threat to maritime security and the global economy.” 

Iranian forces seized two Greek tankers in the Gulf on Friday, shortly after Tehran warned it would take punitive action against Athens over the confiscation of Iranian oil by the United States from a tanker held off the Greek coast.
