North Korea fired several ballistic missiles into the sea after South Korea and the U.S. kicked off their first major joint military exercise of President Donald Trump’s second term.

North Korea launched multiple ballistic missiles into its western waters on Monday, hours after South Korea and the United States commenced their largest annual military exercises. South Korea's Joint Chiefs of Staff said the missile launches originated from the North's southwestern Hwanghae province and landed in the Yellow Sea west of the Korean Peninsula.

North Korea launched several ballistic missiles toward the Yellow Sea on Monday afternoon, Seoul's military said, on the first day of a large-scale joint U.S-South Korea military exercise on the Peninsula.
