Tokyo says North Korea’s seventh round of weapons tests in two weeks may have been launched from submarine

North Korea has fired two short-range ballistic missiles toward its eastern waters, the latest of its recent barrage of weapons tests, a day after Pyongyang warned the redeployment of a US aircraft carrier near the Korean peninsula was inflaming regional tensions.

South Korea’s joint chiefs of staff said in a statement that it detected two missile launches between 1.48am and 1.58am on Sunday local time from the North’s eastern coastal city of Munchon. It added that South Korea’s military has boosted its surveillance posture and maintains a readiness in close coordination with the US.
