A United States Navy carrier strike group was headed towards the Korean Peninsula last week as America strengthens its defences against North Korea's elevating nuclear threats.
The show of strength comes amid mounting tension, with a United States aircraft carrier group steaming towards the region.
If the United States wages reckless provocation against us, our revolutionary power will instantly counter with annihilating strike, and we will respond to full-out war with full-out war and to nuclear war with our style of nuclear strike warfare.
China is seeking Russia's help to cool surging tensions over Pyongyang's nuclear ambitions, the country's foreign minister has told his Moscow counterpart, after Beijing warned of possible conflict over North Korea.
North Korea recently test-fired four ballistic missiles and claims it's close to perfecting an intercontinental ballistic missile and nuclear warhead capable of reaching the US mainland.
A rocket-themed float makes its way through Kim Il-Sung square during a mass rally marking the 105th anniversary of the birth of late North Korean leader Kim Il-Sung, in Pyongyang on April 15, 2017.
In this image made from video broadcast by North Korean broadcaster KRT, North Korea's leader Kim Jong Un salutes during a parade at Kim Il Sung Square in Pyongyang, Saturday, April 15, 2017.
A surprise at the parade was the appearance of Kim Won Hong, who was among the senior government officials joining Kim Jong Un at the podium.
The move, coupled with the U.S. retaliatory strikes against Syria over a chemical weapons attack on civilians, has sparked fear in South Korea that the United States was preparing for military action on the North.
A massive military parade in Pyongyang celebrated the Day of the Sun, April 15, which is the birthday of North Korea's late founder Kim Il Sung.
Pyongyang has also expressed anger over the ongoing annual spring military exercises the USA holds with South Korea, which it considers a rehearsal for invasion.
Kim Jong Un has engaged in a war of words with President Trump amid recent missile tests.
State television showed what appeared to be several KN-08 missiles rolled out on trucks at the parade.
It has carried out five nuclear tests -- two of them past year -- and multiple missile launches, one of which saw several rockets come down in waters provocatively close to Japan last month. Liquid-fueled missiles can't move as easily and so tend to be sitting ducks, if the USA or another country chose to take them out.
For outside military analysts, though, the highlight is the weaponry that the North puts on display. This would allow North Korea to prevent its limited number of ICBM-capable launcher trucks from being damaged during launches and also make the missiles harder to detect after they're fired, he said.
"Our toughest counteraction against the USA and its vassal forces will be taken in such a merciless manner as not to allow the aggressors to survive", the military statement said, according to the North's state-sponsored KCNA news agency.
Another missile launch or nuclear test "can't be ruled out", he said, but the recent United States cruise missile strike on Syria and Washington's tough stance "may give Pyongyang some pause".
