A South Korean medical service team has gotten back to work at a reopened joint inter-Korean industrial park after a five-month hiatus triggered by escalating tensions between the two Koreas, a hospital official said Wednesday. Paik Hospital, a general hospital, pulled its 10-person medical team out of the industrial park in the North Korean city of Kaesong in early April amid the North\'s continued denial of entries by South Korean workers and vehicles into the industrial zone. The hospital started providing the service in January, mainly catering to South Koreans working in the zone but also providing emergency medical service for North Korean employees.
