India on Wednesday expressed "deep concern" following reports that North Korea has conducted a nuclear test.
"We have seen reports that DPRK (Democratic People's Republic of Korea) has conducted a nuclear test today," external affairs ministry spokesman Vikas Swarup said in response to a question.
He said New Delhi was "assessing the available information, including claims that this was a thermonuclear test".
North Korea on Wednesday announced that it has successfully conducted its first hydrogen bomb test.
"It is a matter of deep concern that DPRK has again acted in violation of its international commitments in this regard," Swarup said.
"We call upon DPRK to refrain from such actions which adversely impact on peace and stability in the region. Our concerns about proliferation links between northeast Asia and our neighbourhood are well-known," he added.
