SpaceWar.com reports: “North Korea fired two short-range ballistic missiles but one launch failed, South Korea’s military said Monday, a day after Pyongyang warned of ‘fatal consequences’ following major joint exercises in the South.

South Korea’s Joint Chiefs of Staff said the military had detected two launches, the first at 5:05 am (2005 GMT) and the second around 10 minutes later.

‘The short-range ballistic missile launched at around 05:05 flew approximately 600 km (372 miles),’ it said, adding the second one travelled 120 km.

JCS spokesperson Lee Sung-jun said the second missile appeared to fly abnormally in an early stage of flight, adding that if it had exploded in mid-air, its trajectory indicates debris could have landed over North Korea.

Seoul’s military has ‘strengthened surveillance and vigilance in preparation for further launches’, JCS said in a statement.

North Korea is accused of breaching arms control measures by supplying weapons to Russia to use in its war in Ukraine, and Russian President Vladimir Putin held a summit with leader Kim Jong Un in Pyongyang in June in a show of unity.

The JCS’s Lee declined to comment when asked whether the North’s latest launch could have been a test of missiles intended for delivery to Russia…”
