North Korea launched a missile over Japan early on Tuesday morning, according to officials. Tokyo warned citizens in the north of the country to take cover in basements. This was reported by NHK channel.
Japan's warning system J-Alert advised citizens on its northern Hokkaido island to take precautions, as the missile headed towards land in what was a significant escalation of Kim Jong-un's military posturing.
The missile later broke into three pieces and landed in the sea. It flew for around 1,700 miles, reaching a maximum altitude of 350 miles, South Korean officials reported. The Pentagon confirmed the launch.
The missile was fired from the vicinity of Sunan in Pyongyang at 5:57 a.m. and flew east, according to the Joint Chiefs of Staff (JCS), according to Yonhapnews agency.
"It passed through the sky over Japan," the JCS added.
The North's provocation came three days after it launched three projectiles which the allies regard as short-range ballistic missiles.
As it was reported earlier North Korea launched three medium-range ballistic missiles. One missile, most likely, exploded immediately after the launch, and the other two were out of action already in flight.
The launch of several North Korean missiles was carried out from the eastern coast of the DPRK from the province of Gangwon. Missiles fell in the Sea of Japan.
