North Korea is warning its southern neighbors and the United States that it is not making "empty talk" on its nuclear capabilities.
The rhetoric came in a commentary published on the state-run Korean Central News Agency (KCNA) which condemned South Korea and the United States for the joint 11-day Freedom Shield exercise held last month.
The piece accused the South and the U.S. of being "warmongers" and "going to the extremes."
"Their war hysteria is running up to the climax along with the start of Ssangyong, a joint landing drill," the commentary read.

The author also took issue with forthcoming plans by the South and the U.S. to stage their largest-ever "combined joint firepower annihilation drill" in June, commemorating the 70th anniversary of their alliance.
"This reminds the people and army of the [Democratic People’s Republic of Korea] of June 1950 when they had to be subject to war calamity, and further arousing their high vigilance," the commentary read.
It added: "The U.S. and its followers should never forget the fact that their rival state has possessed the nuclear attack capability in practice as well as the characteristics of the people and army of the DPRK, which do not make empty talk."
North Korea has long been irked by military drills held in the South. Last month, North Korean leader Kim Jong Un called on his country to be ready to launch a nuclear attack to deter war.

His remarks, carried on KCNA, came after the North launched a short-range ballistic missile toward the sea. The missile flew across the country and landed in the sea off its coast, according to South Korean and Japanese assessments – which reported that missile traveled a distance of about 500 miles.
