South Korea on Sunday claimed North Korea fired several cruise missiles from its east coast, media reports said.

The latest firing happened just days after Pyongyang test-fired new strategic cruise missiles from the west coast.

The Joint Chiefs of Staff (JCS) told Yonhap news agency that the North's launch took place around 8 am 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 as quoted by Yonhap.

The strategic cruise missiles fired on Wednesday were named Pulhwasal-3-31.

The missiles were fired towards the Yellow Sea.

Experts told Yonhap news agency that the Pulhwasal-3-31 appears to be a nuclear-capable cruise missile, considering that the number in its name is identical to that of the Hwasan-31, a tactical nuclear warhead that North Korea first unveiled in March 2023
