Fierce fighting in war-torn Yemen's Marib province between government forces and Huthi rebels killed around 50 combatants, including a special forces commander, a government source said Saturday. "Twenty-two members of the government forces and more than 28 rebels have died in the last 24 hours in the fighting that continues unabated on the fronts in Marib province," a government source said. Huthi rebels, who have been trying to capture Marib for more than a year, resumed their offensive against the last major toehold in the north for Yemen's Saudi-backed government on February 8. faw/sy/tp/sw/
