US stealth fighters fly close to N. Korean border
Four US F-22 stealth fighters, accompanied by four US and South Korean warplanes, conducted a flight on Wednesday morning in South Korean airspace near the North Korean border. The eight fighters then landed at Osan airbase near Seoul. The planes joined the squadron deployed to South Korea, including B-52 heavy bombers, after the start of the latest crisis sparked by Pyongyang's missile and nuclear tests. South Korean President Park Geun-hye said Tuesday in an unusually blunt speech that North Korea's steps may lead to the collapse of Kim Jong-un's regime.
