North Korea has confirmed it "successfully" conducted a third nuclear test at a northeastern underground test site, in defiance to UN Security Council’s orders to shut down its atomic activity.

"It was confirmed that the nuclear test that was carried out at a high level in a safe and perfect manner using a miniaturized and lighter nuclear device with greater explosive force than previously did not pose any negative impact on the surrounding ecological environment," the state-run Korean Central News agency (KCNA) said.

The country had been threatening to carry out the test for weeks, in response to sanctions imposed after its successful rocket launch in December last year.

The nuclear test, North Korea's first since leader Kim Jong-un came to power in December 2011, is pressing the UN Security Council to hold emergency talks on Wednesday.
