SEOUL, Aug. 5 (UPI) -- South Korea began antisubmarine drills near its western sea border with North Korea where a South Korean warship was sunk in an attack blamed on Pyongyang.
South Korea's Joint Chiefs of Staff said the five days of drills that began Thursday involve about 4,500 troops from all four military branches, the Dokdo amphibious landing ship, a submarine and a KDX-II class destroyer, plus about 50 fighter jets, the Yonhap news agency reported.
