The South Korean military detected “trajectories” which are believed to be artillery shots fired by North Korea on Sunday evening.
There was no information on the exact number of shots or the origin of projectiles in a text message sent by the Joint Chiefs of Staff (JCS) to reporters, which was cited by Yonhap.
“While bolstering our military’s surveillance and vigilance, South Korea and the United States are working closely and maintaining a thorough readiness posture,” the JCS said, as quoted by the news agency.
According to the Yonhap’s source, a total of two trajectories were detected, with the shots presumably fired from multiple rocket launchers.
North Korea has apparently tested a range of missiles already this year, all of which are banned under the United Nations Security Council’s resolutions.
On June 12, the South Korean military said Pyongyang had fired projectiles from multiple rocket launchers. A week prior to that, the DPRK allegedly fired eight short-range ballistic missiles eastward from four different areas.
The suspected launches have occurred amid intensifying fears in Seoul that North Korea could soon conduct its seventh nuclear test. In June, Sung Kim, the US special representative to North Korea, claimed that Pyongyang could conduct such a test “at any time.”
Several days ago, South Korean President Yoon Suk-yeol warned the neighboring country that any “provocation” would be met with a swift response. He put his country’s military on higher alert amid growing tensions with the DPRK on Wednesday.
