North Korea 'fires two projectiles' off east coast into sea

North Korea fired two unidentified projectiles from the eastern coastal city of Wonsan on Monday, South Korea's defence ministry said.

"The military is monitoring for additional launches and maintaining readiness," said South Korea's Joint Chiefs of Staff.

They were unable to confirm how far the projectiles flew or whether it was ballistic or rocket artillery.

The launches come just days after North Korea's Kim Jong-Un oversaw military drills.
