-- A senior Russian Foreign Ministry official said on Tuesday that North Korea's artillery attack on a South Korean island was unacceptable and called on both sides to show restraint to prevent a wider conflict. "We think the use of force on the Korean peninsula, and in international relations in general, is a path that is absolutely unacceptable," the official told reporters on condition his name was not published. "We think any dispute between North and South Korea must be decided exclusively by diplomatic means," the official said. "Now it is important that the situation does not cross over into a military conflict."
-- South Korea's defence ministry said on Tuesday that North Korea's firing of artillery shells was a clear violation of an armistice between the two countries, and said Pyongyang had planned the shelling intentionally. "This is an intentional and planned attack... and it is clearly in violation of the armistice," Lee Hong-ki, South Korea's defence ministry official, told reporters.

-- The White House on Tuesday condemned an artillery attack by North Korea on a South Korean island and demanded the action cease. "The United States strongly condemns this attack and calls on North Korea to halt its belligerent action," the White House said in a statement.
