South Korea Imposes Travel Bans On Suspects

South Korean police and military investigators imposed travel bans on three civilians accused of flying drones into North Korea, opening a probe after Pyongyang reported incursions on Sept. and Jan. 4. Investigators said the suspects include a graduate student who confessed, a suspected builder and a company employee, and have widened the inquiry after links to the former presidential office and online outlets issuing fake IDs surfaced; authorities seek charges under aviation and military-base protection laws.
