BTS

Their latest hit song "Dynamite" was nominated for the Best Pop Duo/Group Performance category, alongside stars like Lady Gaga and Taylor Swift.

The group posted a reaction video on Twitter, showing them cheering when their nomination was announced.

K-pop expert Jeff Benjamin tweeted that the Grammy nomination was a "huge long-awaited moment in their careers".

He added that it marked a major moment for diversity for "music's biggest night" - which will be held on 31 January.

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.

Big Hit Entertainment, the company behind the pop band, says it is taking action over posts "that exceed the reasonable and accepted boundaries of expression and personal commentary".

The firm did not go into detail about the nature of the comments.

However, it has previously sued over claims of "sajaegi" - bulk-buying albums to inflate BTS's chart position.

Earlier this summer, the company also asked for court authorisation to seize and destroy bootleg merchandise being sold outside the band's concerts.
