SEOUL, Jan. 28 (Yonhap) – North Korea fired several cruise missiles from its east coast on Sunday, the South Korean military said, days after Pyongyang test-fired new strategic cruise missiles from the west coast.

The Joint Chiefs of Staff (JCS) said the North’s launch took place around 8 a.m. in waters off Shinpo Port, but did not elaborate, citing an ongoing analysis.

“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 marks the North’s second cruise missile launch this year after it test-fired strategic cruise missiles, named Pulhwasal-3-31, toward the Yellow Sea on Wednesday.
