“As activity in the Red Sea has heated up this month, debate rages on in Washington about Tehran’s role in attacks against US forces there. The Pentagon confirmed this month that the Iranian-backed Houthi rebels in Yemen were responsible for launching cruise missiles at the USS Mason on Oct. 9 and 12, while it still investigates a potential third attack on Oct. 15. The confirmed attacks, which prompted US strikes against Houthi installations on the coast, were reportedly in retaliation for US backing of the Saudi-led coalition aimed at expelling them from the capital.”
