North Korea is lashing out at the the United States, charging that military drills with South Korea show Washington is not serious about peace.

Major General Kwak Chol Hui with the North's National Defense Commission blasted the ongoing U.S. war games with Seoul during a news conference in Pyongyang Saturday.

“The true character of the U.S. is double faced, advocating dialogue on the surface, while aiming at the military overthrow of its dialogue partner from behind.”

He also warned North Korea troops were ready to “shower of fire of revenge” on U.S. forces.

Also Saturday, state-run television showed images of North Korean leader Kim Jong Un visiting the country's strategic missile command.

Pyongyang's fiery rhetoric follows an deal announced earlier that calls for the U.S. to deliver food aid to North Korea. In exchange, North Korea is supposed to freeze its nuclear activities.

South Korea and the United States began an annual, joint military exercise Monday, despite threats from North Korea that it would launch a “sacred war” if its territory is encroached upon.

South Korea and the U.S. regularly hold military exercises to bolster their readiness against possible North Korean aggression. Still, the North routinely denounces military drills in the South as rehearsals for invasion.
