New Delhi: Joining the world in condemning the testing of a hydrogen bomb by reclusive state North Korea, India on Wednesday described the development as a matter of deep concern.
Expressing concern over the hydrogen bomb test, the Ministry of External Affairs called upon North Korea to refrain from actions which affect peace.
North Korea announced this morning that it had carried out a "successful" hydrogen bomb test - its first.
"The republic`s first hydrogen bomb test has been successfully performed at 10:00 am (0330 GMT)," North Korean state television announced.
"With the perfect success of our historic H-bomb, we have joined the rank of advanced nuclear states," it said, adding that the test was of a miniaturised device.
A hydrogen, or thermonuclear device, uses fusion in a chain reaction that results in a far more powerful explosion than the fission blast generated by uranium or plutonium alone.
Last month, North Korean leader Kim Jong-Un suggested that Pyongyang had already developed a hydrogen bomb.
