The Houthi rebels, prominently in news recently due to attacks on shipping, are primarily based in which country?
Correct: C
The Houthi rebels (Ansar Allah) are an Iran-backed Shiite Islamist political and military organization that emerged in northern Yemen in the 1990s. They have been engaged in a civil war in Yemen and recently escalated attacks on international shipping in the Red Sea in response to the Gaza conflict.
