Russia voices concern over new tensions on Korean peninsula

MOSCOW (Reuters) - Russia voiced concern on Monday over rising tension on the Korean peninsula after the North and South traded artillery fire and what it said was a declaration by Pyongyang that it may conduct a new nuclear test. "We are worried about the mutual toughening of rhetoric, including the declaration by North Korea that it could conduct a new nuclear test," the Foreign Ministry said in a statement urging restraint and criticizing the United States for holding military exercises with South Korea which it said were aggravating the situation.
