North Korea has fired multiple unidentified missiles, it is being reported tonight.
The Yonhap news agency made the claim citing South Korean military's Joint Chiefs of Staff.
The projectiles were launched from North Korea's Hodo Peninsula in South Hamgyong Province on its east coast.
South Korean Military says it is monitoring the situation in case of additional launches.
It comes the country fired two missiles in Kim Jong-un's latest show of force - and one was a new type that flew almost 435 miles before crashing into the sea.
The missiles were launched from Wonsan - a city on the eastern coast - as Pyongyang carried out its first test since its leader and US President Donald Trump agreed to resume talks about denuclearisation and sanctions.
With one projectile travelling almost 435 miles, it was one of the furthest distances a North Korean missile has flown during a drill.
Kim's test risks further escalating tensions in the area and threatens to derail talks after he and Trump met at the demilitarised zone (DMZ) between the two Koreas at the end of June.
South Korea's military said one of the missiles launched last Thursday appeared to be a new type.
The missiles were fired as John Bolton, Trump's national security adviser, visited ally South Korea to discuss regional security.
In May, Kim watched through binoculars and was pictured laughing and smiling as North Korea test-fired two missiles.
Pyongyang's state media said that drill was intended for the country's western "frontline defenders" to demonstrate their ability to carry out "combat missions".
It said "true peace and security of the country is guaranteed only by the powerful physical force capable of defending its sovereignty".
It added: "(Kim) stressed the need to further increase the capability of the defence units in the forefront area and on the western front to carry out combat tasks and keep full combat posture to cope with any emergency."
The report following the launch in May said Kim had "set forth important tasks for further increasing the strike ability".
Kim and Trump met at the DMZ in June, and agreed to hold a new round of talks following two earlier summits in Singapore and Vietnam.
The sides have not agreed to dates or a location.
Since then, North Korea has blasted the US and South Korea over their plans to stage another round of joint military drills.
Pyongyang considers the drills a preparation for invasion.
Last week, KCNA reported Kim inspected a large, newly built submarine, accompanied by missile programme leaders.
Kim was said to have shown great satisfaction with the construction of "our kind of powerful submarine".
However, defence experts claimed the 'new' submarine was actually a refurbished Soviet relic.
Analysts noticed that the vessel was strikingly similar to the Type-033 Romeo, a Soviet submarine from the 1950s.
