U.S. tells Russia: Ukraine intervention risks dangerous escalation

WASHINGTON (Reuters) - U.S. Defense Secretary Chuck Hagel told his Russian counterpart on Saturday that Moscow's military intervention risked creating further instability and an escalation "that would threaten European and international security," the Pentagon said. "Secretary Hagel stressed that, without a change on the ground, Russia risks further instability in the region, isolation in the international community and an escalation that would threaten European and international security," Pentagon spokesman Rear Admiral John Kirby said in a statement, describing the call with Russian Defense Minister Sergei Shoigu.
