SEOUL (Reuters) -The missiles fired by North Korea on Wednesday were a test of a new "railway-borne missile system" designed as a potential counter-strike to any forces that threaten the country, state news agency KCNA reported on Thursday.

The missiles flew 800 km (497 miles) before striking a target in the sea off North Korea's east coast, KCNA said.
