King Jong Un marks delivery of 250 nuclear-capable missile launchers

North Korea has deployed 250 ballistic missile launchers to its southern border, with leader Kim Jong Un describing the weapons as a "powerful treasured sword" to defend its sovereignty, state media said Monday.

The olive green mobile launchers were displayed during a special "transferring" ceremony in the capital Pyongyang on Sunday, the official Korean Central News Agency reported.

The missile launchers were an "up-to-date tactical attack weapon", Kim was quoted as saying in a speech.
