This combined photo, released Oct. 20, 2021, by North Korea's official Korean Central News Agency, shows a new type of a submarine-launched ballistic missile (SLBM) being test-fired from waters the previous day, South Korea's Yonhap News Agency reported.

The South Korean military said on Oct. 19 that North Korea fired what appears to be an SLBM toward the East Sea from waters east of Sinpo, a city on the North's east coast, the agency further reported.

North Korea has carried out a flurry of missile tests in recent weeks, including of what it said were hypersonic and long-range weapons, reports BBC.

The UN Security Council will discuss North Korea's latest missile launches on Wednesday, a source in the Security Council told Sputnik.

"The UK and Ireland called for discussion," the source said.
