North Korea threatens to cut ties with South

North Korea has threatened to end all relations with South Korea, a major supplier of aid and cash to the impoverished state, Yonhap news agency reported on Thursday, quoting official North Korean media.

The move comes days after North Korea said it would resume taking apart its nuclear plant that makes bomb-grade plutonium and return to a disarmament-for-aid deal.
