UNITED NATIONS (AP) — North Korea is warning that its military forces will respond if the U.N. Security Council questions or condemns the country over the sinking of a South Korean navy ship — an act it vehemently denies.

North Korea's U.N. Ambassador Sin Son Ho told a news conference Tuesday there is "a touch-and-go situation that war may break out at any time" because of South Korean accusations that the North torpedoed the ship and killed 46 sailors.

Sin accused South Korea and the United States of cooking up the accusation against the North and demanded that a military investigation team from Pyongyang be permitted to go to the site of the sinking, which the South has refused to allow.
