The vessel, now missing for three days, has triggered a patrol and reconnaissance mission by the Houthis, as reported by UAE-based Al-Ain news website.
"Iranian experts and senior Houthi security leaders participated in a special meeting held in Sanaa to review and discuss a report on the large boat that was lost in the Red Sea," the report said, citing informed sources.
For years, Iran has been accused of supplying the Houthis with weapons and expertise for developing long-range missiles and drones. The shipments, often disguised as commercial vessels, have sometimes been intercepted by the US Navy and other international forces.
Security sources in Yemen revealed to Al-Ain that the Houthi militias lost contact with the large transport boat that was on a smuggling mission via a regular sea route from the Horn of Africa countries to the coasts of the governorate overlooking the Red Sea.
The news outlet said Yemeni security sources confirmed the ship was expected to arrive in Yemen on Friday but disappeared on Saturday. The Houthis, lacking a robust navy, have mobilized small boats and drones for the search, but their fishing boats lack the necessary technology for such operations. No distress calls have been detected.
