North Korea fires several cruise missiles off east coast

North Korea fired several cruise missiles off the east coast on February 14, the South Korean military said.

The Joint Chiefs of Staff (JCS) said it detected the missiles launched at around 9 a.m. into waters northeast of Wonsan on the east coast. It did not specify the number of missiles, Yonhap reports.

"While strengthening our monitoring and vigilance, our military has been closely coordinating with the United States to monitor additional signs of North Korea's provocations," the JCS said in a text message sent to reporters.

It marked the North's fifth cruise missile launch this year.

On Jan. 24, North Korea test-fired a new strategic cruise missile capable of carrying a nuclear warhead, named Pulhwasal-3-31, for the first time.

The country fired submarine-launched cruise missiles off the East Coast on Jan. 28 and conducted two more rounds of tests involving Hwasal-2 strategic cruise missiles from the West Coast in the same week.

Cruise missiles, powered by jet engines, fly low and manoeuvre, making them harder to detect and intercept.

Hwasal means an "arrow" in Korean, and Pulhwasal means a "fire arrow."

Experts believe the North's unusually fast pace of cruise missile tests is aimed at enhancing the performance of the missiles capable of carrying nuclear warheads, which could pose a serious threat to South Korea.
