North Korea fired several cruise missiles off its east coast on Wednesday, Seoul's military said, the latest in a string of weapons tests this year, reports BSS.
"Our military detected several unknown cruise missiles over the waters northeast of Wonsan around 09:00 today (1200 GMT) and South Korea-US intelligence authorities are conducting a detailed analysis," the Joint Chiefs of Staff said in a statement.
It added that it was "strengthening surveillance and vigilance, and closely watching for any additional signs and activities from North Korea".
Earlier this week, North Korea announced it had tested of a new control system for a multiple rocket launcher it said would have an "increased" battlefield role.
So far this year, Kim has declared South Korea his country's "principal enemy", jettisoned agencies dedicated to reunification and outreach, and threatened war over "even 0.001 mm" of territorial infringement.
Pyongyang has also been ramping up weapons tests, including an "underwater nuclear weapon system" test and the firing of a solid-fuelled hypersonic ballistic missile.
It has also launched a flurry of cruise missiles, prompting speculation from experts that it is testing the weapons before shipping them to Moscow for use in Ukraine.
Pyongyang and Moscow have bolstered ties in recent months, with leader Kim Jong Un making a rare trip to Russia to meet President Vladimir Putin in September.
Seoul and Washington have accused the North of supplying Russia with weapons in exchange for Moscow's technical support for Kim's nascent satellite program, which would violate a raft of UN sanctions on both regimes.
Unlike their ballistic counterparts, the testing of cruise missiles is not banned under current UN sanctions on Pyongyang.
Cruise missiles tend to be jet-propelled and fly at a lower altitude than more sophisticated ballistic missiles, making them harder to detect and intercept.
