SEOUL, South Korea (AP) North Korea on Sunday fired two suspected ballistic missiles into the sea, South Korea and Japan said, continuing a streak of weapons launches that suggests leader Kim Jong Un is trying to strengthen domestic support amid worries about a possible coronavirus outbreak in the country.

South Koreas Joint Chiefs of Staff said it detected the projectiles flying from the North Korean eastern coastal city of Wonsan into the waters between the Korean Peninsula and Japan on Sunday morning. The projectiles flew about 143 miles at a maximum altitude of 19 miles, the statement said.

The military described the launches as very inappropriate at a time when the world is battling the coronavirus outbreak. It urged North Korea to stop such military action.

Japans Defense Ministry said that presumed ballistic missiles were believed to have splashed into the sea outside of Japans exclusive economic zone.

Recent repeated firings of ballistic missiles by North Korea is a serious problem to the entire international community including Japan, a ministry statement said.

In recent weeks, North Korea has fired a slew of missiles and artillery shells into the sea in an apparent effort to upgrade its military capability amid deadlocked nuclear talks with the United States. Those weapons were all short range and capable of striking South Korea, but didnt pose a direct threat to the U.S. homeland.

Some experts say the latest North Korean launches were likely designed to shore up unity and show that leader Kim Jong Un is in control in the face of U.S.-led sanctions and the global pandemic.
