Secretary of State Marco Rubio has accused Iran of flying Islamic Revolutionary Guard Corps personnel into Yemen, linking Tehran directly to the worsening Houthi threat. His remarks frame the latest tensions as part of a broader regional struggle involving Iran, Saudi Arabia and the Iran-backed rebel movement.

According to Rubio, Iran’s actions helped spark a renewed confrontation between Saudi Arabia and the Houthis. The accusation suggests Washington believes Tehran is doing more than offering political backing, and is instead playing an active operational role inside Yemen.

The statement puts fresh attention on the IRGC’s alleged presence in the country at a time of rising instability. It also reinforces long-running U.S. concerns that Iran uses allied groups across the region to project power and pressure rival governments.

Rubio’s comments are likely to add to diplomatic strain around the Yemen conflict and the wider Saudi-Iran rivalry. With the Houthi threat escalating, the accusation adds another layer to an already volatile regional security picture.
