North Korea has threatened to launch strikes against its enemy South Korea and the US, to pre-empt an attack by the two countries on its nuclear facilities.
The threat follows an agreement between Seoul and Washington over the introduction of nuclear deterrents against Pyongyang.
Under the US-South Korea agreement, the two countries vowed to attack North Korea if there are indications it will use its nuclear weapons. The strategy is being dubbed as “customised deterrence”.
North Korea has denounced the agreement and said it will not hesitate to attack US and South Korean interests if they resort to “such military provocations”.
