The parade, the annual highlight of North Korea's most important holiday, came amid growing worldwide worries that North Korea may be preparing for its sixth nuclear test or a major missile launch, such as its first flight test of an ICBM capable of reaching US shores.
North Korea rolled out intercontinental ballistic missiles and other military hardware at a massive parade on Saturday to celebrate the birthday of the country's late founder, as third-generation leader Kim Jong Un looked on in delight. In a test launch in August previous year, the missile flew 500 kilometers (310 miles) after being launched from a submarine and crashed into waters near Japan, prompting Kim Jong Un to declare that North Korea had gained "perfect nuclear-attack capability".
"We're prepared to respond to an all-out war with an all-out war and we are ready to hit back with nuclear attacks of our own style against any nuclear attacks", Choe Ryong-Hae said in a speech at a ceremony before a large military parade started.
The show of military might came as the U.S. Navy sent the USS Carl Vinson strike group to the region.
The state TV also showed several KN-08 missiles being rolled out on trucks at the parade.
Ostensibly Saturday's event was to mark the 105th anniversary of Kim Il-Sung's birth - a date known as the "Day of the Sun" in the North - and a squadron of warplanes flew overhead forming the number. An official from South Korea's Defense Ministry couldn't immediately confirm whether any of the rockets represented a new type of ICBM.
But if the parade signaled a readiness for war, North Korea has long insisted that its goal is peace - and survival - with the growing arsenal a way to ensure that the government in Pyongyang is not easily overthrown.
"Though analysts questioned what was inside the missile shells, they said the appearance of a submarine-launched ballistic missile shows North Korea is progressing with its plan to launch missiles from anywhere in the sea".
DPRK stands for the official name of North Korea, the Democratic People's Republic of Korea. North Korean leader Kim Jong Un has appeared.
"Military analysts paid close attention to two new types of intercontinental ballistic missiles enclosed in canister launchers mounted on the backs of trucks - none of which had been displayed before".
The North's Korean People's Army (KPA) added its voice to the bellicose rhetoric yesterday with a statement threatening strikes against United States military bases and other targets in South Korea. These missiles concern South Korea because they're harder to detect before launch than liquid-fuel missiles, which need to be filled with fuel before launch and also require fuel trucks and other vehicles that could be spotted by satellites.
But now Pyongyang has threatened an "annihilating strike" if Trump "wages reckless provocation against us".
China, North Korea's sole supporter, has stepped in to calm the rising tensions.
Other senior officials joining Kim at the podium included Kim Won Hong, who the South Korean government had said earlier this year was sacked from his job as state security minister, presumably over corruption. The North also a year ago launched a long-range rocket that put a satellite into orbit, which Washington, Seoul and others saw as a banned test of missile technology.
