This latest weapons seizure will be another example of forces inside Iran stoking sectarian tensions in the Middle East if the U.S. assessment proves correct. Iran was sending weapons to aid the Houthis in their fight against Saudi Arabia. The Houthis are Shiite Muslims, as are most Iranians. Yemen's government has been dominated by Sunni Muslims and has been supported by Sunni nations such as Saudi Arabia and Egypt. While Iran does not have control over the Houthi militia, it has provided them with support to include on the ground advising, training, weapons, and large sums of money. Currently Saudi Arabia is fighting against the Houthi in Yemen.
Iran and Saudi Arabia continually try to extend their influence and ideology throughout the Middle East in order to undermine each other. Examples of this are" In Lebanon Iran backs Hezbollah, in Syria, Iran backs the Assad regime, in Iraq Iran backs the Shia government.
