TEHRAN, April 24 (MNA) – North Korea says the US military exercise with South Korea is driving the regional security environment into dangerous turmoil.North Korean Leader’s sister Kim Yo Jong, scrutinizing a series of joint live-fire drills by the United States and South Korea, made the remarks on Wednesday.

“We will continue to build overwhelming and the most powerful military power to safeguard our sovereignty, security, and regional peace.” Her comments came after North Korea early Tuesday carried out its first nuclear counterattack drills to simulate its "nuclear trigger" management system.

During the maneuver, North Korea fired several short-range ballistic missiles toward the sea off its east coast.

The drill comes as a clear warning against Washington as it enhances its regional presence and boosts military alliance with North Korea and Japan.

The countries have expanded training and trilateral drills in the South China Sea.
