The official KCNA news agency of the Democratic People's Republic of Korea (DPRK) on Friday accused the United States and its military allies of taking "a grave action of aggression quite contrary to the global trend for peace."

The United States is "entirely to blame for the situation" on the Korean Peninsula that was on the brink of war as Washington used the peninsula to realize its strategy to dominate East Asia, said the KCNA in a commentary.

The United States, which focused its efforts on knocking into shape a triangular military alliance with Japan and South Korea to hold hegemony in the Asia-Pacific, "put the alliance into test" by escalating the situation on the peninsula this year, it said.

The U.S., Japan and South Korea demonstrated "unprecedented joint actions" in reacting to the Cheonan warship case and the island shelling incident by employing "every means and method to add fuel to fire" to escalate the conflict, it said.

Japan and South Korea are acting as "shock brigades" for realizing the U.S. strategy for aggression, it added.

The commentary also called on the international community to take as an urgent matter to return stability and peace to Northeast Asia and to "foil the U.S. moves to round off alliance for aggression."
