North Korea 'test-fires missiles'

North Korea has test-fired four short-range missiles into the sea off its west coast, say South Korean military officials.

In a statement, the Joint Chiefs of Staff (JCS) said the missiles had a range of about 140km (87 miles).

They were fired from Dongchang-ri in the north of the country on Friday afternoon local time, it said.

The North often conducts missile tests in protest at US-South Korean military drills, one of which is ongoing.
