U.S. deploys F-22s to South Korea as part of joint military exercises
North Korea said it was entering a "state of war" with the South
Seoul views the threat from Pyongyang in "a serious manner"

Seoul, South Korea (CNN) -- The South Korean president on Monday warned North Korea that any provocative moves will be met with "a strong response" as the United States deployed stealth fighter jets in the tense region as part of joint military exercises.

"If there is any provocation against South Korea and its people, there should be a strong response in initial combat without any political considerations," President Park Geun-hye said at a meeting with senior defense and security officials, according to her office.

Her comments came after North Korea rattled off fresh volleys of bombastic rhetoric over the weekend, declaring that it had entered a "state of war" with the South and labeling the U.S. mainland a "boiled pumpkin," vulnerable to attack.
