North and South Korea have fired a number of missiles into waters near each other’s coasts in a marked escalation of hostilities.
The North launched its most missiles in a single day – at least 23 – including one that landed less than 60km (37 miles) off the South’s city of Sokcho.
Seoul responded with warplanes firing three air-to-ground missiles over the disputed maritime demarcation line.
Later Pyongyang fired six more missiles and a barrage of 100 artillery shells.
The North says the launches are in response to large-scale military exercises current being held by South Korea and the United States, which it calls “aggressive and provocative”.
On Tuesday, Pyongyang warned they would pay “the most horrible price in history” if they continued their joint military drills, seen as a veiled threat to use nuclear weapons. The North has tested a record number of missiles this year as tensions have risen.
