N. Korea beefs up guard at nuclear test site: report

SEOUL (Reuters) - North Korea has increased security around a site where it conducted a nuclear test last year, South Korea's Yonhap news agency reported on Sunday.

"Intelligence information was obtained that guards were being reinforced at the nuclear test site, along with (additional fencing)," it quoted an unnamed South Korean government source as saying.

"South Korea and U.S. authorities are keeping a close watch on the area and analysing the North's intentions."

But the source dismissed the likelihood of a second test at the Gilju site in North Hamkyung province, citing Pyongyang's pledge to the international community to disable its nuclear facilities.

North Korea marked the first anniversary of the nuclear test on October 9 that made it globally ostracised and the target of painful sanctions.
