North Korea threatened today to 'impose the death penalty' on the South's former president Park Geun-Hye over an alleged plot to assassinate its leader Kim Jong-Un.

Park had 'pushed forward' a supposed plan by Seoul's intelligence services to eliminate the North's leadership, Pyongyang's security ministry and prosecutors said in a statement carried by its official Korean Central News Agency.

"We declare at home and abroad that we will impose death penalty on traitor Park Geun Hye," it said. -- Agencies
