North Korea could strike US from space - expert

North Korea could be planning to strike the United States from space with an electromagnetic pulse (EMP), a security expert warns.

Dr Peter Vincent Pry, executive director of the Task Force on National and Homeland Security, claims two satellites are already orbiting the earth.

Dr Pry told The Independent North Korea's capital, Pyongyang, may be secretly developing the ability to detonate a high-altitude nuclear weapon in space, wiping out electrical systems below.

North Korea is believed to have started a satellite programme during the 1980s and successfully launched two observation satellites in 2012 and 2016.

Dr Pry's comments follow months of building tension between the two countries.

There are doubts North Korea has the technology to launch a direct attack on the US, but Dr Pry says they're getting closer - and have hover a satellite overhead as a bargaining chip.
