Yemen Security Brief:

The US Navy seized 70 tons of ammonium perchlorate in the Gulf of Oman on November 15.[i] The ammonium perchlorate was bound for Yemen from Iran. Ammonium perchlorate is used to make rocket and missile fuel. The US Navy’s 5th Fleet commander said 70 tons of ammonium perchlorate could fuel “more than a dozen medium-range ballistic missiles.” This was the 5th Fleet’s first interdiction of ammonium perchlorate. 

Yemeni news outlet South24 reported on November 15 that Saudi Arabia offered the Houthis $150 million to pay salaries in Houthi-controlled ministries.[ii] The Houthis reportedly rejected the offer. Saudi Arabia briefed the Yemeni president about the offer but offered the money unilaterally.
