North Korea on Friday fired what appeared to be two short-range ballistic missiles in its third weapons launch this month, officials in South Korea said, in an apparent reprisal for fresh sanctions imposed by the Biden administration for its continuing test launches.

South Korea’s Joint Chiefs of Staff said the missiles were fired 11 minutes apart from an inland area in western North Pyongan province, where North Korea is known to operate key missile bases and has frequently conducted test launches in recent years.

The missiles flew 430 kilometers (267 miles) cross-country on a maximum altitude of 36 kilometers (22 miles) before landing in the sea, the military said.

Japan’s coast guard urged vessels to pay attention to falling objects, but Chief Cabinet Secetary Hirokazu Matsuno said there were no reports of damage to vessels or aircraft.
