SEOUL, South Korea -- North Korea declared Saturday it has entered "a state of war" with South Korea in the latest of a string of threats that have raised tensions on the Korean Peninsula.
North Korea's government, parties and organizations said in a joint statement that all matters between the two countries will now be dealt with in a manner befitting war.
The Korean Peninsula is already in a technical state of war because the Korean War ended in a ceasefire, not a peace treaty. But Pyongyang ditched that armistice earlier this month.
South Korea's Unification Ministry quickly released a statement calling the latest threat not new and saying it is a follow-up to Kim's earlier order to put troops on a high alert in response to annual U.S-South Korean defence drills. Pyongyang sees those drills as rehearsals for an invasion.
On Friday, North Korean leader Kim Jong Un warned his forces were ready "to settle accounts with the U.S." after two American B-2 bombers flew a training mission in South Korea.
Analysts say a full-scale conflict is unlikely and even suicidal for Pyongyang and the threats are aimed at drawing Washington into talks. But the threats from North Korea and rising animosity from the rivals that have followed UN sanctions over Pyongyang's Feb. 12 nuclear test do raise worries of a misjudgment leading to a clash.
On Friday at the main square in Pyongyang, tens of thousands of North Koreans turned out for a 90-minute mass rally in support of Kim's call to arms. Small North Korean warships, including patrol boats, conducted maritime drills off both coasts of North Korea near the border with South Korea earlier this week, South Korean Defence Ministry spokesman Kim Min-seok said in a briefing Friday. He didn't provide details.
The spokesman said South Korea's military was mindful of the possibility that North Korean drills could lead to an actual provocation. He said the South Korean and U.S. militaries are watching closely for any signs of missile-launch preparations in North Korea. He didn't elaborate.
Pyongyang uses the U.S. nuclear arsenal as a justification for its own push for nuclear weapons. It claims that U.S. nuclear firepower is a threat to its existence and a provocation.
