North Korea says it simulated nuclear strike on South

North Korea says it has fired two short-range tactical ballistic missiles to simulate nuclear strikes on military targets in South Korea.

State media said the tests had been conducted as a warning against the US deployment of strategic bombers to the region.

South Korea reported two missiles landing in the sea.

The launches coincide with annual joint military drills held by South Korea and the US.

Pyongyang has long denounced the drills as a war rehearsal.
