K-pop boy band

The boy band performed in front of a sell-out crowd at King Fahd International Stadium in Riyadh on Friday evening.

However they faced criticism for their decision to play in a country that has been condemned for human rights abuses.

BTS is one of the world's biggest acts - the first Korean pop group to reach number one on the US album charts.

Known for their meticulously choreographed dance style and boyish good looks, they boast a huge and devoted fan base.

The band had been invited to play in the country by Saudi Crown Prince Mohammed Bin Salman.

Jonghyun, full name Kim Jong-hyun, was one of the five members of Shinee, who have had a string of number one hits in their home country.

The Korea Herald said the singer was taken to hospital after being found unconscious in an apartment in Seoul. He was 27 years old.

Police told the BBC Korean Service that suicide will be investigated as a possibility.

Emergency services were alerted by the singer's sister and he was later pronounced dead at hospital.
