Yemen's Houthi rebels have been attacking ships in the Red Sea, one of the world's major trade arteries. Attacks have increased since the Israel-Hamas war broke out in October, and Israeli-linked vessels have been targeted. But recent missile strikes have hit vessel withouts any obvious Israeli ties, raising concerns about widening risks. Oil prices haven't reacted so far. But experts say insurance costs for shippers moving oil, grain and consumer goods through the waterway have doubled. A shipping industry representative says the industry is nervous but he doesn't foresee the Houthis shutting transport through the Red Sea.
