A photograph of the youngest victim of the plane crash in South Korea has emerged showing him staring out of an aircraft’s window.

Ko Yoonwoo was pictured travelling to Bangkok with his parents on what was his first holiday abroad. He was killed when his return flight, a Jeju Air plane with a total of 181 people on board, crashed on Sunday.

The three-year-old died alongside his parents Kang Ko, 43, and Jin Lee Seon, 37.

The picture of Yoonwoo had been posted by his father on Instagram alongside other holiday snaps of the family. An earlier post showed the toddler at the airport next to his passport.

The caption said: “My son is going abroad for the first time on a night flight, and his first passport has no stamp!”
