The conflict took on an international dimension late in the month. Clashes were reported between the Houthis and Saudi security forces near the border. Also, Yemeni officials captured a boat in the Red Sea that was transporting anti-tank shells and, according to some reports, five Iranian instructors sent to help the Houthis. Various official Iranian sources responded, calling this claim a politically motivated fabrication, and stating that the ship was traveling for business activities carrying no consignment. In early November the rebels stated that Saudi Arabia was permitting Yemeni army units to launch attacks from across the border at a base in Jabal al-Dukhan, charges which were denied by the Yemeni government. In late October, heavy clashes in the area of Razih led to the Houthis capturing two military headquarters and killing Yemeni General Amr Ali Mousa Al-Uuzali. In early November, General Ali Salem al-Ameri and regional security chief Ahmed Bawazeir were killed in a Houthi ambush as they were returning from Saudi Arabia.
