Seoul: North Korea fired an unidentified ballistic missile eastward on Monday, South Korea's military said, marking its second launch in a week.

The Joint Chiefs of Staff said it detected the launch but gave no further details, saying an analysis is underway.

The latest launch comes after North Korea fired a ballistic missile toward the East Sea on Wednesday, Yonhap news agency reported.

North Korea claimed to have successfully conducted a multiple warhead missile test, but South Korea has dismissed the claim, saying the launch failed as the missile exploded in the air.
