South Korea’s President Park Geun-hye has warned that inter-Korean relations could destabilize following the imposition of a “reign of terror” that on Sunday saw Jang Song Thaek being arrested for multiple anti-party and anti-state crimes.

Her warning, made at a cabinet meeting held in Seoul on Tuesday, came amid continued and increasingly critical North Korean media coverage of Jang Song Thaek’s “elimination” from the party.

“North Korea is currently engaged in a reign of terror while carrying out massive purges in order to consolidate Kim Jong Un’s power. The South-North relations could become more unstable in the future,” Park said
