|US and S Korea begin joint drill|
The joint naval and air drills, code-named "Invincible Spirit", began on Sunday and came four months after the sinking of a South Korean warship that has been blamed on the North.
About 8000 US and South Korean troops, 20 ships and submarines and 200 aircraft are taking part in the drill, which the US and South Korea have said is aimed at curbing the North's "aggressive" behaviour.
The exercises will be held in South Korean and international waters over the next four days and have prompted an angry reaction from Pyongyang, which has described the exercise as an "unpardonable military provocation", and threatened to counter it by using their "powerful nuclear deterrence".
