MOSCOW, January 6./TASS/. Kremlin is extremely worried about North Korea’s announcing it carried out a hydrogen bomb test, Kremlin spokesman Dmitry Peskov told a news conference on Wednesday.
"President Vladimir Putin has given instructions to thoroughly study data of all monitoring stations, including seismic, and analyze the situation in case the information about the test is confirmed," he said.
Earlier on Wednesday, North Korea announced a successful test of a thermonuclear bomb. The country’s government said in a statement circulated by the Korean Central News Agency (KCNA) the test had had "no adverse impacts on the environmental situation. Now, according to the statement, North Korea "possesses the strongest deterrent forces."
North Korea previously conducted three nuclear tests: in 2006, in 2009 and in 2013. Following these tests, the United Nations Security Council imposed different kinds of sanctions on Pyongyang. In the past two years, North Korea refrained from nuclear tests limiting itself to ballistic missile launches as a response to South Korea’s and the United States’ large-scale military exercises.
North Korea’s leader Kim Jong-Un said on December 10 the country had a hydrogen bomb of its own.
