In Yemen, fighters with the Houthi movement have escalated their offensive against government forces with fierce clashes in the province of Taiz. The fighting has left dozens of Yemeni government troops dead in recent weeks. That has reportedly prompted Saudi Arabia to consider support for a Yemeni government counteroffensive to retake the Houthi-held Red Sea coast. The renewed fighting in Yemen comes as an unclassified Pentagon assessment of civilian casualties found the U.S. killed 153 civilians in Yemen last year, while wounding another 243.
