North Korea has upped its war talk once again, warning the United States it faces an "unimaginable" military strike.
The Kim Jong-un regime was reacting to the continued drills being carried out by the US and South Korea in the region.
Next week the allies will carry out Courageous Channel in which Americans in the area will practice being evacuated in the event of a "crisis".
Although it is carried out twice a year, it has heightened fears of military conflict.
North Korea's state news agency said in a statement: "The US is running amok by introducing under our nose the targets we have set as primary ones.
"The US should expect that it would face unimaginable strike at an unimaginable time."

Last week, North Korea was spotted moving multiple missiles sparking fears of a fresh launch.
A US spy satellite captured images of missiles mounted on launchers being moved out of a hangar near the capital Pyongyang last Friday, it was claimed.
American and South Korean intelligence agencies are now preparing for the Kim Jong-un regime to carry out a new provocation in defiance of worldwide condemnation.
It had been expected the most likely date for a new missile launch would be October 10, the anniversary of Kim's political party.
But that date passed without any notable military movements.
However the new satellite images suggest Kim will go ahead with another test of its intercontinental ballistic missiles.
A source told South Korean newspaper The Dong-A Ilbo: "The North may carry out a simultaneous launch of ICBM and IRBM within a few days in protest against the U.S.'s show of military might."
The US and her ally South Korea have carried out a series of military drills recently.
Two US Air Force supersonic heavy bombers were flown over the Korean peninsula , despite threats from North Korea to shoot down American planes.
Two B-1B Lancers based in Guam flew a mission in the vicinity of the Sea of Japan, staging the first night-time joint aviation exercises with Japan and South Korea.

In response, Kim Jong-un ’s government warned the joint exercise had ‘hardened our determination that the U.S. should be tamed with fire’.
The government said the military drills ‘lets us take our hand closer to the trigger for taking the toughest countermeasure’.
In August, North Korea threatened to fire a salvo of intermediate range missiles toward the U.S. Pacific island territory.
Guam is a major military hub and home to U.S. bombers that periodically fly missions over the divided Korean Peninsula.
Yesterday, White House Chief of Staff John Kelly said there’s ‘great concern’ about Americans who live in Guam.
Speaking at a White House news conference he said: “Right now we think the threat is manageable. Let’s hope that diplomacy works.”

The fresh threat was published in North Korean state media.
It also said that North Korea has ‘already warned several times that we will take counteractions for self-defence including a salvo of missiles into waters near the US territory of Guam’.
It is unlikely to have any effect on next week’s planned major joint-navy drill between Sourth Korea and the U.S.
In a statement the US 7th Fleet said the USS Ronald Regan aircraft carrier and two US destroyers would take part in the drill alongside South Korean Navy vessels.
