Satellite images have emerged that appear to show activity at one of North Korea's submarine bases days after it threatened to carry out a missile test towards US-owned Guam.

"Recent commercial satellite imagery reveals several developments suggesting that North Korea may be accelerating the development of the sea-based leg of its nuclear forces", he was quoted by AFP news.

The Pukguksong-1 is an SLBM that was first successfully test-launched in August past year.

On Aug. 5, the United Nations Security Council voted unanimously for fresh sanctions on North Korea, after it launched two ICBM tests last month, which has prodded Pyongyang to threaten a missile strike around the USA territory of Guam.

He had flown about 500 km in the direction of Japan, which had led the north Korean leader Kim Jong-un to assert that the us mainland was now within range of a submarine crossing the Pacific.

This comes just a day after open warning by the American President Donald Trump saying-things will happen to the country like it "never thought possible" if Pyongyang thinks about attacking America or any of its allies.

The renewed tensions followed the progress of Pyongyang in its nuclear and missile programs.

The news about preparations for a submarine-launched ballistic missile test come as tensions between the U.S. and North Korea are escalating over the latter's vigorous efforts to gain nuclear weapons technology and successfully launching an intercontinental ballistic missile (ICBM) that theoretically could hit USA mainland cities.
