The massive ordnance was launched after the green light was given by North Korean leader Kim Jong-Un.
It was airborne for 45minutes, and travelled 1,000km before landing in the Sea of Japan, according to the Pentagon.
Jong-Un is attempting to send a message to President Donald Trump and neighbouring South Korea over his military might – and refusal to end his nuclear programme.
After the missile launch yesterday (July 28) Japanese authorities scrambled to check the safety of boats and planes in the exclusive economic zone, according the nation’s chief cabinet secretary Suga.
Video has now emerged appearing to show the warhead falling from the sky just 100 miles from the Japanese mainland.
The clip was filmed in Murrain City – on the country’s east coast on Friday.
A bright light can be spotted in the distance, which lights up the sky for several seconds.
Defence analyst, Kim Dong-yub, at the Institute for Far Eastern Studies at Kyungnam University in Seoul said the missile “would easily reach the West Coast of the United States with a range of 9,000 to 10,000 kilometres”.
London is just 8,608km from North Korea.
If the calculated distance is correct- it means Britain’s capital could be struck by North Korea.
However, for now it seems Donald Trump is the man in the sights of Kim Jong-Un.
President Donald Trump labelled the test as “only the latest reckless and dangerous action by the North Korean regime”.
Japan said it would “consider” military action and Trump said the US is now considering using force in response to the latest test.
North Korea’s testing of an intercontinental ballistic missile has been condemned by Foreign Secretary Boris Johnson.
The Foreign Secretary warned Pyongyang that Britain and its allies would confront the “growing threat” posed by the country.
Mr Johnson said: “The UK strongly condemns North Korea’s second test of an intercontinental ballistic missile and calls on the regime to immediately stop all activity that breaches UN Security Council resolutions.
“The UK will stand alongside our allies and partners as we confront the growing threat North Korea poses to regional and international security. Once again North Korea shows no regard for its international obligations.
“We urge the DPRK regime to put the well-being of its own people ahead of the illegal pursuit of nuclear and ballistic missile programmes.”
The intervention came after North Korean dictator Kim Jong Un said the second test of an intercontinental ballistic missile demonstrated his country can now hit the US mainland.
