N Korea launches ballistic missile towards sea after threatening US over alleged spy flights

North Korea launched a ballistic missile toward its eastern waters on Wednesday, its neighboUrs said, two days after the North threatened “shocking” consequences to protest what it perceived a provocative U.S. reconnaissance activity near its territory.

South Korea’s Joint Chiefs of Staff says the launch was made on Wednesday morning but gave no further details such as how far the weapon flew.

Japan’s Defense Ministry said it also detected a possible ballistic missile launch by North Korea.

The launch, the North’s first weapons firing in about a month, came after North Korea earlier this week released a series of statements accusing the United States of flying a military plane close to North Korea to spy on the North.

The United States and South Korea dismissed the North’s accusations and urged it to refrain from any acts or rhetoric that raises animosities.

In a statement on Monday night, Kim Yo Jong, the influential sister of North Korean sister Kim Jong Un, claimed that the U.S. spy plane flew over the North’s eastern exclusive economic zone eight times earlier in the day. She claimed the North scrambled warplanes to chase away the U.S. plane.

North Korea has made numerous similar threats over alleged U.S. reconnaissance activities, but its latest statements came amid heightened animosities over North Korea’s barrage of missile tests earlier this year.
