A US aircraft carrier led joint military exercises with South Korea Sunday, dpa reported. The USS George Washington, several guided-missile destroyers from both navies and more than 200 aircraft were enlisted for the four days of manoeuvres that include 8,000 personnel from the two allies. "Some ships from the US 7th Fleet, including a nuclear-powered submarine, are set to join them in the East Sea," one official told Yonhap news agency. Planned drills included artillery, anti-submarine charges and air-to-air refueling, an official at the South's Joint Chiefs of Staff said. "As an exercise to prevent attacks like the sinking of the Cheonan, we will drop sea mines and anti-submarine bombs during Tuesday's drill," Yonhap quoted the official saying.
