North Korea fired two cruise missiles into the Yellow Sea on Wednesday, just under a week after Kim Jong Un paved the way for more weapons tests by declaring victory in his country’s battle against COVID-19.

The South Korean military said it had detected the two launches from the Onchon area, near the North’s western coast, the Yonhap news agency reported, citing an anonymous defense official in Seoul.

The official did not provide further details, including the exact type of missiles and launch times, but added that South Korean and U.S. intelligence authorities were conducting an analysis.
