North Korea’s foreign ministry blasted Australia on Wednesday over “outrageous infringement” of the DPRK’s sovereignty, warning Canberra’s “hostile acts” threaten peace in the region.

The statement comes as Australia, the U.S. and Japan conclude an annual aerial combat training exercise called Cope North in Guam and after Australian Foreign Minister Marise Payne condemned North Korea’s recent string of missile launches, calling for the full enforcement of sanctions on the DPRK until it denuclearizes.
