The latest launches began at 07:30am (local time) at a site near Mount Myohyang, northeast of Pyongyang, with two fired in the morning and another two in the afternoon, all towards the Sea of Japan (East Sea), the ministry said.
‘The type of the projectiles is not known,’ a ministry spokesman told AFP.
‘The test of two projectiles launched in the morning appeared to be unsuccessful because they just flew for several seconds, while two other projectiles fired in the afternoon travelled for up to 210 kilometres (126 miles),’ he said.
The ministry declined to confirm a Yonhap news agency report that the North might have tested new 300-millimetre multiple rocket launchers.
The exercise came as cross-border military tensions run high following a series of missile, rocket and artillery launches in recent weeks.
North Korean leader Kim Jong-Un guided a missile-firing drill last Saturday after the United Nations Security Council condemned Pyongyang for its recent ballistic missile tests in violation of UN resolutions.
