North Korea: Fresh test could trigger radioactive leak, South says

A fresh nuclear test at North Korea's mountainous testing site could trigger a leak of radioactive material, South Korea's chief meteorologist has warned.

A hollow space of up to 100m in length in the bottom of Mount Mantap could implode, Nam Jae-cheol said.

Pyongyang's last nuclear test in early September appeared to have triggered several landslides. "There is a hollow space, which measures about 60 to 100 metres in length, at the bottom of Mount Mantap in the Punggye-ri site," Mr Nam was quoted by South Korean news agency Yonhap as saying. "Should another nuke test occur, there is the possibility of a collapse," he warned.

The Punggye-ri test site, situated in mountainous terrain in the north-east of the country, is thought to be Pyongyang's main nuclear facility and the only active nuclear testing site in the world.
