The United States sent a request to hold a meeting of the United Nations Security Council on May 11 on the situation with North Korea’s missile tests, a source in the organization told TASS on Monday.

"The US has requested a meeting late in the afternoon on Wednesday," the source said.

According to the South Korean Committee of Chiefs of Staff, North Korea launched one short-range ballistic missile at the Sea of Japan on May 7. It flew for roughly 600 kilometers and reached a maximum altitude of 60 kilometers.

On May 7, Japan's Coast Guard announced that North Korea has fired what is believed to be a ballistic missile.

"According to the information of the defense ministry, North Korea has carried out the launch of, presumably, a ballistic missile. Vessels are asked to monitor up-to-date information and, if fragments are detected, not to approach them and notify the coast guard," Sputnik reported.
