SHAH ALAM, Malaysia — A Vietnamese woman charged in the airport assassination of the half brother of North Korea’s leader, Kim Jong-un, was sentenced on Monday after pleading to a lesser charge of causing bodily harm.

The defendant, Doan Thi Huong, 30, was one of two women who smeared VX nerve agent on the face of Kim Jong-nam, Kim Jong-un’s elder brother, in February 2017. She was ordered to serve 40 months in prison.

But her lawyer said she would be released on May 4, after time served and an additional sentence reduction.

Her co-defendant, Siti Aisyah, 27, was freed three weeks ago after intensive lobbying by the Indonesian government, including a personal appeal from President Joko Widodo to Malaysia’s prime minister, Mahathir Mohamad.
