Pyongyang propaganda outlet DPRK Today said Tuesday, local time, the United States and South Korea are escalating tensions, and the alleged threats have placed the entire People's Army on standby, South Korean news service Newsis reported.
"At present the People's Army soldiers cannot repress the rising anger in the face of the U.S. and South Korean military aggressors, who are spreading tensions from a West Sea hot spot to the Han River Estuary."
North Korea did not provide further details, but it's likely DPRK Today was referring to United Nations Command actions in South Korean waters in mid-June.
The U.N. Command had conducted a joint action, deploying a military police unit and four speedboats near the border with North Korea, in order to evict Chinese boats fishing illegally in South Korea and neutral waters.
The North Korean propaganda outlet also included photographs of the Hwasong-10 ballistic missile launch, which ran with the statement, "Words are never understood by invaders."
"We have the clear capability to realistically attack the enemy within the Pacific Operations Zone," Pyongyang said in its statement.
The Hwasong-10 is also known as the Musudan missile, known to have a range between 1,800 and 2,500 miles.
