North Korea fiercely accused the Obama administration Thursday of deliberately raising tensions on the Korean Peninsula, while refraining from criticizing South Korea.

Recounting security-related events in Korea this year, the Korean Central News Agency claimed a military crisis has returned to Korea due to Washington's "hostile policy" on Pyongyang.

"The current U.S. administration's policy on the DPRK and its implementation is the most hostile and ferocious in the history (of the U.S. government)," it said. The DPRK stands for the Democratic People's Republic of Korea, the communist nation's official name.

The state-controlled mouthpiece warned that if the U.S. sticks to its existing stance, it will face the North's "response beyond imagination." It did not elaborate.

The KCNA argued that the U.S. was behind the August landmine incident along the inter-Korean border that maimed two South Korean soldiers.

The two Koreas were in sharp military stand-offs amid concerns about the possibility of an armed clash, though they averted the crisis through marathon talks between the top officials of the two sides.

The KCNA said the South's military initially admitted that the blast was an accident involving landmines washed away by rain, but it later blamed the North at the instruction of the U.S. authorities. (Yonhap)
