An official group of the Democratic People's Republic of Korea (DPRK) on Friday accused South Korea of preparing a war against its country, the official Korean Central News Agency reported.
The Committee for Peaceful Reunification of the Fatherland, an official DPRK group, criticized South Korea for developing "ultra-modern weapons of various types" and setting up a new "command for guided shells."
South Korea, who followed the United States, was pursuing a hostile policy against the DPRK, said the statement.
"This dangerous arms build-up indicates that the south Korean military bellicose forces are putting spurs to the preparations for a war against the north," it said.
"We will never remain a passive on-looker to their frantic preparations for a war against the north, but strongly react to them," it added.
Meanwhile, the leading official newspaper Rodong Sinmun warned that the inter-Korean relations were heading toward an "irreversible breakdown," due to South Korea's hostile policy.
The reaction came one day after U.S. President George W. Bush's meeting with his South Korean counterpart Roh Moo-hyun in Washington, with both sides calling on the DPRK to return to the six-party talks aiming at resolving the nuclear issue on the peninsula.
The DPRK last month condemned an annual joint US-South Korea military drills, saying the exercises could lead to an actual war and warning it had the right to take "preemptive" measures in self-defense.
Seoul and Washington said the exercises, which had been held annually since 1975, were for defense.
Bush had linked the DPRK with Iran and Saddam Hussein's Iraq as an "axis of evil."
Since the 1950-1953 Korean war, U.S. troops have been stationed in the South.
This year's exercise, which concluded on September 1, involved 9,000 U.S. troops and an undisclosed number of South Korean soldiers.
