Malaysian Prime Minister Najib Razak said on Thursday that the body of Kim Jong Nam, half brother of North Korean leader Kim Jong Un, has been released to North Korea, bringing an end to a diplomatic spat that escalated over nearly seven weeks.

Najib said nine Malaysians barred from leaving North Korea had been allowed to board a plane to leave Pyongyang, adding on Twitter that the plane was expected to reach Kuala Lumpur at 5 a.m. Malaysian time.

The Malaysians left Pyongyang in a Royal Malaysian Air Force business jet, which headed immediately west out of North Korean airspace before turning south toward Malaysia, according to flight tracking website planefinder.net.
