North Korea on Tuesday fired several suspected cruise missiles towards the sea, the South's military said.
The "multiple projectiles" fired from Munchon in the east of the country were believed to be "short-range cruise missiles," the Joint Chiefs of Staff said in a statement.
The test comes a day before the nuclear-armed North marks the 108th anniversary of the birth of its founder Kim Il Sung, grandfather of the current leader Kim Jong Un.
It also comes a day before the South holds parliamentary elections, and at a time when the world's attention has been largely focussed on the coronavirus pandemic, which Pyongyang insists it has so far escaped.
The North has repeatedly tested ballistic missiles in recent years, which climb high above the Earth, often into space, before being brought down towards their targets at high speed by the force of gravity.
Its arsenal includes ICBMs (intercontinental ballistic missiles) that are capable of reaching the whole of the US mainland.
In contrast cruise missiles travel at low altitudes -- sometimes just a few metres (feet) above the surface, making them hard to detect -- and are powered throughout their flight.
Sometimes highly manoeuvrable, they need sophisticated guidance systems to bring them to their targets.
Tuesday's missiles travelled over the Sea of Japan, also known as the East Sea, before coming down in the water, the JCS said.
"South Korea and US intelligence authorities are closely analysing related issues," they added.
The North is subject to multiple UN Security Council sanctions over its banned weapons programmes.
The latest launch came after the South Korean and US militaries began mainly computer-simulated joint exercises on Monday to test Seoul's ability to take operational control in wartime.
Kim said the latest missile test was “an occasion to send an adequate warning to the joint military drill now underway by the US and South Korean authorities,” according to KCNA.
It was North Korea’s first known testing activity in months, underscoring how the country continues to expand its military capabilities amid a stalemate in nuclear negotiations with the United States.
The police said that the bombs hidden inside three minibuses from public view in different districts of the city.
The infant suffered 2 weeks of constant vomiting and pain before the real cause of her pain was discovered. It turned out that the girl swallowed the magnets from a toy she was playing with.
People who come in close contact with an infectious person, including health workers, family members and sexual partners, are at greater risk of infection.
