Leaders slam 'outrageous' threat to 'sink' Japan
A North Korean threat to sink Japan with a nuclear bomb is "outrageous", Japan's government spokesman said.
A statement from an organisation called the Korea Asia-Pacific Peace Committee attacked the United States for leading a push for stronger UN sanctions against North Korea, and railed against Japan for backing the US campaign.
"The four islands of the (Japanese) archipelago should be sunken into the sea" by a nuclear bomb, the statement reads in part.
Japan's chief cabinet secretary Yoshihide Suga said the statement "significantly escalates tension in the region and is absolutely unacceptable".
The UN Security Council unanimously approved new sanctions on Monday after North Korea carried out its sixth and strongest nuclear test on September 3.
