SOCHI, Russia — Four Ukrainian women gave their politically torn country some good news at the Sochi Games on Friday, and Canada delivered more bad news to the United States — yet another Olympic hockey defeat. As government and opposition leaders worked to end the months-long Ukrainian crisis that erupted in deadly violence this week, the Ukraine women's 4x6-kilometer biathlon relay team won the nation's first gold medal in two decades. The four women celebrated with a Ukrainian flag as lawmakers back home paused to mark the occasion.
