There was increased speculation today that North Korea might be preparing for nuclear tests, after satellite images and intelligence reports hinted at increased activity near nuclear test sites.
North Korean leader Kim Jong Un "made an important decision that will serve as a guiding principle in defending the country's security and sovereignty," the North's official KCNA news agency reported on Sunday, according to South Korean newspaper Chosun Ilbo.
On Jan. 31, South Korean media reported that Kim Jong Un had issued martial law in the North and declared that a nuclear test would take place sometime between last week and this Tuesday.
Following revelations that the North Korean military is covering up one tunnel to prevent satellite observation, GlobalPost senior correspodent Geoffrey Cain reports that "there's activity at a second site at Punggye-ri, the purported nuclear test area."
"They've concluded that North Korea could, therefore, be getting ready to detonate two bombs at the same time or back-to-back, perhaps to demonstrate their power," Cain reported from Seoul.
If the allegation turns out true, it would be significant. This signifies that the pariah state is not using highly enriched uranium, as was discovered early last year, but that it's gone so far to produce two pretty sophisticated, expensive bombs when you consider its level of poverty.
Chosun Ibo quoted a military official as saying, "There is a chance that the southern tunnel is a decoy, but we are not ruling out that the regime will conduct nuclear tests simultaneously at both tunnels," according to The Daily Telegraph.
Yu Woo-ik, South Korea's unification minister, said the North is likely to carry out what would be its third round of nuclear testing, though he gave no time-frame.
"If the North Korea nuclear test takes place, it is a provocation against the international community. This is a major provocation against South Korea," said Kim Min-seok, a spokesman for the defense ministry, according to Al Jazeera.
