SEOUL (Reuters) -- South Korea and the United States staged their first combined military exercises involving an American aircraft carrier in more than four years, Seoul's military said on Saturday, amid reports that North Korea was preparing for a nuclear test.
The three-day drills took place in international waters off the Japanese island of Okinawa until Saturday, including air defense, anti-ship, anti-submarine, and maritime interdiction operations, South Korea's Joint Chiefs of Staff (JCS) said.
