Seoul, South Korea (CNN) -- After days of concern about possible North Korean aggression over a South Korean military drill, the live-fire naval exercise ended peacefully after an hour and 34 minutes with no immediate reaction from the North.
North Korea said over the weekend that the drill could ignite a war and that it would respond militarily to the exercise, but the country did not act immediately on Monday.
The North, however, agreed to a series of actions after former U.S. ambassador to the United Nations Bill Richardson urged the country not to respond aggressively.
During the drill, fighter jets took to the sky in preparation for possible retaliation by North Korea, the South Korean defense ministry said.
The South Korean military remained on high alert after the drill ended and is observing the North carefully, the country's Joint Chiefs of Staff said. CNN
