[Updated at 10:35 p.m.] North Korea deployed surface-to-air missiles to near its Yellow Sea border with South Korea days before joint U.S. war exercises with the South were set to get under way on Sunday, South Korea's official Yonhap news agency reported, citing unnamed government sources.
"[North Korea's missiles] appear to be targeting our fighter jets that fly near" North Korea's Yellow Sea border with South Korea, the source said, according to Yonhap.
South Korea and the United States began assembling ships for joint war exercises Sunday off the west coast of the Korean peninsula in the Yellow Sea, a source at the South Korean Joint Chiefs told CNN.
[Original post, 7:51 p.m.] South Korea and the United States have begun war exercises off the west coast of the Korean peninsula, according to South Korea's official news agency Yonhap.
"The drills started around 6 a.m. Sunday with the USS George Washington joining our warships in the Yellow Sea," an official at the South's Joint Chiefs of Staff told Yonhap.
North Korea had warned of unpredictable "consequences" if the United States fulfilled its vow of deploying the aircraft carrier USS George Washington to the Yellow Sea for joint military maneuvers with South Korea.
Earlier this week, North Korea shelled Yeonpyeong Island, killing four South Koreans. North Korea said the South provoked the Tuesday attack because shells from a South Korean military drill landed in the North's waters. South Korea was holding its annual Hoguk military drill when the North started its shelling, and the South returned fire.
The U.S.-South Korean exercises were planned months ago and are meant to underscore strong ties between South Korea and the United States, defense officials from both countries have said.
