North Korea warned South Korea today not to stage artillery drills on a disputed island the North bombed last month, saying it would hit back even harder than in the previous attack that killed four South Koreans.
The North warned the South against similar drills before the it launched an attach that destroyed homes and renewed fears of war on the divided peninsula.
South Korea has said it plans one-day, live-fire drills sometime between Saturday and Tuesday on Yeonpyeong, a tiny island that is home to fishing communities and military bases and sits just 11km from North Korean shores. Seoul says the drills' timing will depend on weather and other factors and, despite the North's threats, the exercises will go ahead as planned.
The North, which claims nearby waters and has said it considers such drills an infringement of its territory, responded to similar firing exercises by raining artillery shells on Yeonpyeong, killing two marines and two construction workers.
The assault was the first by the North to target a civilian area since the end of the 1950-53 Korean War, and it has caused anger and shock in the South, where TV screens and newspapers were filled with stunning images of islanders fleeing their bombed-out, burning homes.
A senior North Korean military official said in comments carried by the North's official Korean Central News Agency that if South Korea goes ahead with more drills on Yeonpyeong, "unpredictable self-defensive strikes will be made."
"The intensity and scope of the strike will be more serious than the November 23rd (shelling)," the North said in the notice that was sent to South Korean military officials today.
The North said the planned drills are an attempt "to save the face of the South Korean military, which met a disgraceful fiasco" during last month's clash.
South Korean president Lee Myung-bak's government has faced criticism that his military was unprepared for the attack and reacted too slowly and too weakly. He has since replaced his defence minister and promised to increase troop numbers and defences on islands along the Koreas' disputed western sea border.
South Korea's defence ministry said today that the North's threats wouldn't stop the planned drills. Seoul has said they are part of "routine, justified" exercises and has warned that it is prepared to deal with any North Korean attack. Representatives of the American-led UN Command that oversees the armistice that ended the Korean War will observe the drills.
The tough words from the Koreas came as a high-profile US state governor visited North Korea.
New Mexico Governor Bill Richardson, who has frequently been an unofficial envoy to the North, said he wanted to visit the North's main nuclear complex and meet with senior officials during his four-day trip, though details of his schedule were unclear. He said ahead of the visit that he expected to get some sort of message from the North.
"My objective is to see if we can reduce the tension in the Korean peninsula," Mr Richardson said at the airport in Pyongyang.
In Washington, State Department spokesman PJ Crowley called the South's exercises routine and said they pose no threat.
In Beijing, US deputy secretary of state James Steinberg held closed-door meetings with Dai Bingguo of the Chinese State Council.
Beijing's most senior foreign policy official returned last week from talks in Pyongyang with North Korean leader Kim Jong Il. China has come under growing pressure to push ally North Korea to change its behavior.
Mr Dai said it was urgent that all parties prevent escalating tensions, according to China's official Xinhua News Agency.
The US special envoy for six-party talks, Sung Kim, met today for talks with South Korean nuclear envoy Wi Sung-lac. Mr Kim did not talk to reporters after the meeting.
Pyongyang is believed to be seeking one-on-one talks with the United States before returning to six-nation nuclear disarmament negotiations hosted by China. Those talks also include South Korea, Japan, and Russia.
