Iran is once again denying aiding Yemen’s Houthi rebels. A commander in Iran’s Revolutionary Guard says the Houthis are independent in making their operational and strategic decisions. Meanwhile, Houthi leader Abdul Malik al-Houthi said, "Now, we will meet escalation with escalation," adding that Yemen's Houthi militants will target U.S. ships in the Red Sea as long as the U.S. continues its attacks on Yemen.
