Yemen war restarts: Saudi-led forces vow to 'eliminate' Houthis

After four years of calm, war has returned to Yemen. On October 4, the Saudi-led military coalition announced a full-scale campaign against the Houthi militia. The coalition, which backs Yemen's internationally recognized government, said on social media that its goal is to "eliminate" the group. The Houthis are a political and armed movement that controls large parts of Yemen, including the capital, Sanaa. They have fought the Saudi-backed government since 2014. Bloomberg's Veena Ali-Khan examined why the Houthis are so difficult to defeat. She spoke with Businessweek Daily hosts Carol Massar and Tim Stenovec.
