North Korea says successfully tested ICBM engine

Seoul: North Korea said Saturday it had successfully tested an engine designed for an inter-continental ballistic missile (ICBM) that would "guarantee" an eventual nuclear strike on the US mainland.

It was the latest in a series of claims by Pyongyang of significant breakthroughs in both its nuclear weapons and ballistic missile programmes.

Outside experts have treated a number of the claims with scepticism, suggesting the North Korean leadership is attempting to talk up its achievements ahead of a showcase ruling party congress next month.

According to the North`s official KCNA news agency, the ground engine test was ordered and personally monitored by leader Kim Jong-Un.

As soon as Kim flagged off the test, "the engine spewed out huge flames with deafening boom", KCNA said."The great success... provided a firm guarantee for mounting another form of nuclear attack upon the US imperialists and other hostile forces," Kim was quoted as saying.

Now North Korea "can tip new type inter-continental ballistic rockets with more powerful nuclear warheads and keep any cesspool of evils in the earth including the US mainland within our striking range", he added.

Military tensions on the divided Korean peninsula have been rising since the North conducted its fourth nuclear test in January, and a long-range rocket launch a month later that was seen as a disguised ballistic missile test.

The UN Security Council responded with its toughest sanctions to date over the North`s nuclear programme, and Pyongyang accused Seoul and Washington of spearheading the sanctions drive in New York.

In recent weeks, the state media has carried repeated threats of pre-emptive nuclear strikes against both the South and the US mainland.The threats have been accompanied by claims of success in miniaturising a nuclear warhead to fit on a missile, developing a warhead that can withstand atmospheric re-entry, and building a solid-fuel missile engine.

North Korea has never tested an ICBM, although it has displayed such a missile, known as the KN-08, during recent mass military parades in Pyongyang.
