SEOUL, April 8 (UPI) -- North Korea launched several short-range ballistic missiles toward the sea between the Korean Peninsula and Japan on Wednesday, Seoul's military said, marking its second launch in as many days after South Korean President Lee Jae Myung expressed regret over a drone incursion.

"The South Korean military detected several short-range ballistic missiles launched from the Wonsan area of North Korea toward the East Sea around 08:50 on April 8," Seoul's Joint Chiefs of Staff said in a text message to reporters.

The missiles flew approximately 150 miles, the JCS said, adding that South Korean and U.S. intelligence authorities are analyzing their exact specifications.

"Under a steadfast South Korea-U.S. combined defense posture, the military is closely monitoring North Korea's various movements and maintaining the capability and readiness to overwhelmingly respond to any provocation," the JCS said.
