Yahoo! News - Powell Says N. Korea Blast Not Nuclear

There was no indication that was a nuclear event of any kind. Exactly what it was, we're not sure," Powell said on ABC's "This Week.

"The explosion happened at 11 a.m. Thursday in Yanggang province near the border with China, Yonhap said.

'We understand that a mushroom-shaped cloud about 3.5 to 4 kilometers (2.1 to 2.5 miles) in diameter was monitored during the explosion,' the news agency quoted an unidentified diplomatic source in Seoul, the South Korean capital, as saying.

Yonhap quoted an unidentified South Korean official as saying seismic activity related to two blasts in North Korea occurred at 11 p.m. Wednesday and 1 a.m. Thursday.

The damage and crater left by the explosion in Kim Hyong Jik county was big enough to be noticed by a satellite, Yonhap quoted an unidentified source in Beijing as saying."
