North Korea fires 'unidentified projectile
North Korea has fired at least one unidentified projectile, South Korea's military says, less than a week after it tested several short-range missiles.
The projectile was fired from the Sino-ri location north of the capital, Pyongyang, toward the east, according to South Korea's Joint Chiefs of Staff.
On Saturday, North Korea launched a number of projectiles from its east coast into the sea.
A US envoy has visited Seoul for talks on how to break the nuclear deadlock.
In February, a meeting in Vietnam between the North Korean leader, Kim Jong-un, and US President Donald Trump, ended without agreement.
President Trump walked away from what he described as a bad deal offered by Mr Kim.

The projectile was fired at about 16:30 local time (07:30 GMT), the South Korean military said, without providing further details.
"We're still analysing whether it is a single or multiple projectiles," spokesman Kim Joon-rak told AFP news agency.
