US Secretary of State Marco Rubio stated on July 22 that Iran was the "troublemaker" of the Gulf region and that any restrictions on Red Sea shipping by Houthi forces would be problematic, likening the situation to the Strait of Hormuz. The comments followed reported threats by Houthi groups to impose a blockade on Saudi vessels and data from ship-tracking sources showing multiple oil tankers altering courses in the Red Sea on or around that date.
Rubio also attributed a central role to Iran in regional tensions, amid unverified claims of prior disruptions to the Strait of Hormuz and redirected Saudi oil shipments.
