North Korea warned the United States on Saturday to end its "military hysteria" or face retaliation as a U.S. aircraft carrier group steamed towards the region and the reclusive state marked the "Day of the Sun", the 105th birth anniversary of its founding father, APA reports quoting reuters.
Concern has grown since the U.S. Navy fired Tomahawk missiles at a Syrian airfield last week in response to a deadly gas attack. That raised questions about U.S. President Donald Trump's plans for North Korea, which has conducted several missile and nuclear tests in defiance of U.N. and unilateral sanctions.
The North's warning came as leader Kim Jong Un, looking relaxed in a dark suit and laughing with aides, oversaw a military parade at Pyongyang's main Kim Il Sung square, named after his grandfather, on his birth anniversary.
Goose-stepping soldiers and marching bands filled the square, next to the Taedonggang River that flows through Pyongyang, in the hazy spring sunshine, followed by tanks, multiple launch rocket systems and other weapons.
Single-engine propeller-powered planes flew in a 105 formation overhead.
North Korea, still technically at war with the South after their 1950-53 conflict ended in a truce but not a treaty, has on occasion conducted missile or nuclear tests to coincide with big political events and often threatens the United States, South Korea and Japan.
"All the brigandish provocative moves of the U.S. in the political, economic and military fields pursuant to its hostile policy toward the DPRK will thoroughly be foiled through the toughest counteraction of the army and people of the DPRK," the KCNA state news agency said, citing a spokesman for the General Staff of the Korean People's Army.
DPRK stands for the official name of North Korea, the Democratic People's Republic of Korea.
"Our toughest counteraction against the U.S. and its vassal forces will be taken in such a merciless manner as not to allow the aggressors to survive."
