'War games' warning to North Korea

The one-day drills south of the heavily armed Korean border involve fighter jets, attack helicopters, armoured vehicles and 2,000 allied troops.
South Korea's Defence Ministry said the drills are to deter a North Korean attack.
Pyongyang calls the exercises preparation for war.
Monday is the 62nd anniversary of the start of the Korean War.
The three-year conflict ended in a truce, not a peace treaty.
Tension is high after a North Korean rocket launch in April.
Pyongyang has also threatened to attack South Korea's government and media for perceived insults.
