Russia calls on South Korea to halt military drill

Russia on Friday urged South Korea to halt plans for an artillery drill that North Korea had said hours earlier would prompt a new strike at the South.

"The Russian Federation insistently calls on the Republic of Korea to refrain from holding the planned firing of artillery in order to prevent the further escalation of tensions on the Korean peninsula," the foreign ministry said.

It said a similar drill on November 23 had "provoked an exchange of fire ... that caused casualties," echoing Pyongyang's assertion that its shelling of an island near a disputed maritime border was a response to South Korean artillery firing.

North Korea said earlier on Friday that it would strike again, with an even stronger response than the shelling that killed four people last month, if Seoul goes ahead with its planned live-firing drill on Yeonpyeong Island on December 18-21.

The Russian statement marked a shift to a tougher line on South Korea's military drills.

When foreign minister Sergei Lavrov met with his North Korean counterpart on Monday, Lavrov said military exercises had added to tension but also that the North's shelling of the island deserved condemnation, according to the ministry.

On Friday, the Russian ministry expressed "deep concern" about South Korea's planned drill and said it was "extremely important" to ease tension between the two Koreas, restore dialogue and resolve all disputes without using force.

Russia, which shares a short border with North Korea, has put its forces in the nation's far east on alert because of the Korean tension, the Interfax news agency cited the chief of the military General Staff as saying on Tuesday.
