North Korea has called the test of two new missiles on Thursday a "solemn warning" against what it described as "South Korean warmongers".

The short-range missiles were fired into the Sea of Japan, also known as the East Sea, from Wonsan on North Korea's east coast.

Leader Kim Jong-un said his country was forced to develop weapons to "eliminate potential and direct threats".

He said the test involved a new tactical guided weapons system.

Mr Kim's comments, reported in state media, come after the North criticised a decision by South Korea and the US to hold military drills next month.
