Sites for possible North Korean nuke tests found

The US and South Korea have pinpointed 11 underground sites in North Korea where it could conduct a third nuclear test, a newspaper reported yesterday ahead of a summit between the two allies on the communist regime's growing atomic threat.
South Korean President Lee Myung-bak departed on a trip to Washington for summit talks Tuesday with President Barack Obama, which are expected to be dominated by the North's nuclear and missile programmes.
Tension on the Korean peninsula spiked after North Korea declared Saturday it would step up its nuclear bomb-making programme by producing more plutonium and uranium, two key ingredients.
The North also threatened war with any country that tries to stop its ships on the high seas as part of new UN Security Council sanctions passed in response to Pyongyang's May 25 nuclear test.
North Korea is believed to have enough weaponised plutonium for at least half a dozen atomic bombs, and a US government official said last week that Pyongyang may be preparing for another nuclear test, its third.
The official spoke on condition of anonymity in order to discuss the unreleased information and provided no details.
US and South Korean intelligence were keeping a close eye on signs of an impending test.
"South Korean and US intelligence authorities have spotted 11 key underground facilities in North Korea and embarked on an intensive lookout," South Korea's mass-circulation JoongAng Ilbo newspaper reported.
It quoted an unnamed government intelligence official as saying the allies have mobilised spy satellites and human intelligence networks to check for vehicle movements and other unusual activity.
The mobilisation is based on "intelligence that North Korea can conduct a third nuclear test in protest against the UN Security Council sanctions," the paper quoted the official as saying.
Also Monday, Yonhap news agency quoted an unidentified intelligence official as saying the North may have already built two to three underground test sites near its known Punggye-ri site in the remote northeast, where it conducted its first and second tests.
South Korea's Defence Ministry and National Intelligence Service said they could not confirm the reports.
A news report from Moscow quoted an official in the Russian military general staff as saying there has been a decrease in visible activity around North Korea's nuclear facilities in recent days.
This could either indicate that the North has prepared for a new underground nuclear test or is taking a break, according to the state-owned RIA-Novosti news agency. It did not name the official, and the general staff could not immediately be reached for comment.
North Korea has also been preparing to fire an intercontinental ballistic missile capable of striking the United States. It says the nuclear and missile programmes are a deterrent against the United States.
However, Washington fears that cash-strapped North Korea will sell its nuclear technology to rogue nations, spreading the atomic threat.
The regime has also warned it cannot guarantee the safety of South Korean and US navy ships sailing near the disputed western sea border, raising the spectre for a maritime confrontation. The area is the scene of two bloody maritime skirmishes between the Koreas in 1999 and 2002.
South Korea's navy chief of staff said a maritime skirmish could occur "at any time" and that his forces were prepared.
"We will cut off the enemy's wrist even if they touch the tip of our finger," Jung Ok-keun said at a ceremony marking a deadly naval clash with North Korea in 1999.
The strong ties between South Korea and the United States are a thorn in the side of wartime foe North Korea, which accuses the two countries of plotting an attack to topple the communist regime. The allies deny harbouring any such intention.
But President Lee of South Korea said his country's ties with the United States are "key" at a time of "intensifying" security crisis because of North Korea's nuclear and missile tests.
"I will use this summit to reconfirm the strong Korea-US alliance," Lee said in a radio speech before his departure.
The two Koreas remain technically at war because their three-year conflict ended in a truce, not a peace treaty, in 1953, and they remain divided by a heavily fortified border. The US has 28,500 troops in South Korea.
The two Koreas signed an accord to ease military tensions and promote economic cooperation nine years ago Monday. However, ties have significantly frayed since Lee, a conservative who advocates a hard-line approach, took office last year. The North responded by cutting off ties and halting joint business projects.
Their last major symbol of cooperation a joint industrial complex in the North also faces an uncertain future after the North demanded a 3,000 percent increase in rent for the site and a fourfold hike in wages for North Korean workers last week.
The Unification Ministry said Monday that South Korean firms operating in the zone have requested 61 billion won ($48 million) in state subsidies to compensate them for dwindling business.
On Monday, a group of South Korean conservative activists sent about 100,000 leaflets by balloons across the border into the North, to criticise its nuclear and missile programmes. Later in the day, about 16,000 conservative activists, retired military officers and others staged an anti-North Korea rally in Seoul with some holding placards that reads "Kim Jong Il should blow himself up."
There were no immediate reports of violence, police said.
