North Korea to seek extradition of anyone involved in 'CIA plot to kill Kim Jong Un'

North Korea will seek the extradition of anyone involved in what it says was a CIA-backed plot to kill leader Kim Jong Un last month with a biochemical poison, a top foreign ministry official said.

Han Song Ryol, the vice foreign minister, called a meeting of foreign diplomats in Pyongyang on Thursday to outline the North's allegation that the CIA and South Korea's intelligence agency bribed and coerced a North Korean man into joining in the assassination plot, which the North's Ministry of State Security has suggested was thwarted last month.
