“Moscow is extremely concerned over information that has appeared that North Korea has tested a hydrogen bomb,” Peskov said.
“President Vladimir Putin has given instructions to carefully study the data of all measurement stations, including seismological stations, and to analyze the situation if information on the tests are confirmed,” Peskov added.
Earlier on Wednesday, an earthquake occurred in South Korea, prompting Seoul`s suspicions that Pyongyang had performed a nuclear test. North Korea subsequently confirmed that it had successfully tested a hydrogen bomb.
