July 31 (Asia Today) -- North Korea warned Friday that a physical military confrontation on the Korean Peninsula had become "a matter of time," criticizing efforts to strengthen the U.S. military command in Japan.

The Korean Central News Agency said in a commentary that the expansion showed U.S. Forces Japan was being transformed into a command center capable of directing American and allied forces throughout the region.

"Today, a physical clash in the Korean Peninsula region is no longer a question of whether it will occur but a question of when," the state-run news agency said.

The commentary apparently responded to remarks by U.S. Forces Japan commander Lt. Gen. Stephen Jost in a recent interview with Japan's Asahi Shimbun.
