Saudi Arabia’s Foreign Minister Prince Faisal bin Farhan Al Saud has expressed concerns over “transgressions by Iran”, particularly in its nuclear program.

According to al-Arabiya, the visiting Saudi diplomat made the remarks at a joint press conference with Greek Foreign Minister Nikos Dendias in Athens on Tuesday.

Prince Farhan pointed out that Iran's activities don’t match with what Tehran declares about “the peaceful nature” of its nuclear program.

He reiterated Saudi Arabia’s support for international efforts to prevent Iran from acquiring nuclear weapons, as Tehran and world powers are negotiating over the revival of their nuclear agreement in Vienna.

Bin-Farhan said that he explained to his Greek counterpart "the Houthi group's threat to international navigation, the latest example of which was the hijacking of a civilian shipat sea."

The Saudi minister made similar comments after his meeting with his Jordanian counterpart Ayman al-Safadi in Amman on Monday, stressing “the importance of intensifying efforts to prevent Iran from acquiring nuclear weapons and make the Middle East free of weapons of mass destruction.”

Riyadh and Tehran held talks last year to reduce tensions with the aim of restoring diplomatic ties broken since January 2016. So far, the talks have been exploratory with no tangible results.
