NKorea Developing Nuke Warhead: Seoul Official -- AFP

SEOUL (AFP) — North Korea is working to develop a nuclear warhead which can fit onto a missile, South Korea's top military officer said Wednesday, according to Yonhap news agency.

"I understand that North Korea is working to develop a small nuclear warhead which can be loaded into a missile," Kim Tae-Young, chairman of the joint chiefs of staff, was quoted as telling legislators.

Kim said he could not say whether or not the communist state has already succeeded in developing such a warhead.
