North Korea has test-fired a ballistic missile, South Korean and US military officials say.
It apparently exploded seconds after lift-off, the South Korean military was quoted as saying by Yonhap news agency. The US military said the missile did not leave North Korean territory.
It was fired from a site in South Pyeongan province north of Pyongyang in the early hours of Saturday local time, South Korea said.
The type of missile is not yet known.
US President Donald Trump tweeted: "North Korea disrespected the wishes of China & its highly respected President when it launched, though unsuccessfully, a missile today. Bad!"
So far there has been no word from North Korea.
Tensions in the region have increased lately, with both North and South Korea conducting military exercises.
North Korea has made repeated attempts to miniaturise nuclear warheads and fit them on long-range missiles capable of reaching the US.
"North Korea fired an unidentified missile from a site in the vicinity of Bukchang in Pyeongannam-do (South Pyeongan Province) early this morning," the South Korean Joint Chiefs of Staff (JSC) said in a statement, Yonhap reports.
It added that the missile apparently exploded, just seconds after the launch.
Meanwhile, Commander Dave Benham, a spokesman for US Pacific Command, said the "launch occurred near the Pukchang airfield (north of Pyongyang)".
He added that the missile did not leave North Korean territory and did not pose a threat to North America.
The launch occurred a matter of hours after the US Secretary of State Rex Tillerson called on the rest of the world to help force North Korea to give up its nuclear ambitions.
Speaking at the UN Security Council, Mr Tillerson warned of "catastrophic consequences" if the Council did not act, saying it was "likely only a matter of time before North Korea develops the capability to strike the US mainland".
The US would use military force if necessary, he said.(Source: BBC)
