North Korea pledged Friday to restore its military communications hot line with the South but closed the border dividing the two Koreas for the third time in recent days, South Korean officials said. The North Korean military cut the communications line on March 9 to protest Seoul's decision to hold 12 days of joint military exercises with U.S. troops across South Korea at a time of heightened tension on the peninsula. Washington and Seoul call the war games routine defense drills; Pyongyang accused the two nations' militaries of preparing to attack the North. The drills ended Friday. The North said it would reconnect the hot line at 8 a.m. Saturday, Unification Ministry spokeswoman Lee Jong-joo said.
