Russia will continue to battle terrorists “without compromise,” President Dmitry Medvedev said Monday, hours after a pair of suicide attacks ripped through Moscow’s metro, killing at least 37 people. “We will continue operations against terrorists, without compromise and to the end,” Mr. Medvedev said at an emergency government meeting.
