North Korea have created a CGI video of its missiles devastating the United States to celebrate the birthday of the nation's founding father.

A large band played as the clip showed four missiles honing in on the US mainland and exploding in a ball of fire.

A crowd of thousands cheered in glee during the party to honour the 105th birth anniversary of Kim Il-sung in North Korea on Sunday.

The American flag and rows of white crosses in a cemetery appeared in flames on the screen.

"All the performers and participants in the military parade broke into enthusiastic cheers of 'hurrah!'," state run KCNA news agency said.

Current dictator Kim Jong Un could be seen waving and congratulating the performers, attracting a standing ovation from the crowd.

"When the performance was over, all the performers and participants in the military parade broke into enthusiastic cheers of 'hurrah!'," state run KCNA news agency said, according to Reuters.

The footage, which was aired on state television, included a real clip of a missile launch in February, when North Korea claimed to have successfully tested the Pukguksong 2 – a solid-fuel propelled, long range weapon.

A day earlier the North Korean military proudly displayed new missiles during a military march before a failed test which attracted international outcry.

The bizarre video comes amid rising military tensions between the US and North Korea.

North Korean officials have warned they are prepared for an "all-out war" and would carry out a pre-emptive strike on the US mainland if there were any signs of aggression from the White House.

Earlier this month, the US Navy struck a Syrian airfield with 59 Tomahawk missiles after a chemical weapons attack.

The US military also dropped the largest non-nuclear device in its history, known as "the mother of all bombs", on caves and tunnels used by Islamic State militants in Afghanistan on Thursday.

North Korea have condemned any US intervention in Syria and Afghanistan. Vice Foreign Minister Han Song-Ryol said the nation will continue to conduct nuclear tests in defiance of United Nations sanctions despite its failed operation this week.

The North Korean military have also claimed it is developing weapons with the potential to hit the US mainland.
