Two supersonic US B-1b "Lancers" have flown over the Korean peninsula in a 'show of force' despite Kim Jong-Un's threats to shoot them down. 

This comes as US President Donald Trump was advised by his national security on how to respond to North Korea's recent missile tests.

Two US B-1 bombers carried out a training exercise last night with Japanese and South Korean military aircraft amid growing tension over North Korea's nuclear programs.

It was the first time US Pacific Command B-1B Lancers have conducted combined training with Japanese and South Korean fighter aircraft at night.

After entering South Korean airspace, the two bombers carried out air-to-ground missile drills in waters off the east coast of South Korea, then flew over the South to waters between it and China to repeat the drill, the release said.

The South Korean military said this was part of a regular exercise to bolster military defences and also to display the alliance between the United States and South Korea.  

The two B-1B bombers were accompanied by two F-15K fighters from the South Korean military after leaving their base in Guam, the South's Joint Chiefs of Staff said in a news release.
