UN 'deeply concerned' over mounting tension over Korean Peninsula

This month, Washington holds the rotating presidency of the UN Security Council and in that capacity has scheduled a ministerial-level meeting on April 28 on the subject of nuclear non-proliferation. The DPRK's nuclear program will be spotlighted.

US Secretary of State Rex Tillerson is expected to chair the session.

"I strongly censure and categorically reject the convening of a briefing on DPRK nuclear issue as another abuse of authority, behavior of double standards and violation of the DPRK's sovereignty by the UN Security Council acting under instructions of the United States," Ambassador Kim said.

"As everybody knows nowadays the US, without any hesitation, perpetrates military attacks and threatens a sovereign state while claiming for 'peace by strength,'" he said. "The recent US massive missile attack on Syria tells you well of it."

"The US is disturbing the global peace and stability and insisting on the gangster-like logic that its invasion of a sovereign state is 'decisive, just and proportionate,'" the ambassador said, referring to Washington's justification for the rain of missiles on a Syrian air base following a chemical weapons attack April 4 on Syrian civilians.

In response to an aircraft carrier-led armada of US naval ships to the seas just east of the DPRK, the ambassador said, "the US introduces into the Korean peninsula, the world's biggest hotspot, huge nuclear strategic asses, seriously threatening peace and security of the peninsula and pushing the situation there to the brink of war."

"This has created a dangerous situation in which a thermo-nuclear war may break out at any moment," he said.
