BTS fans have matched a $1m donation to the Black Lives Matter movement by the group and their label Big Hit Entertainment.
At the weekend, it emerged that BTS and Big Hit had made the donation to help the fight against racism.
The BTS ARMY was then mobilised. It started to trend the hashtag #MatchAMillion on Twitter, to raise the same amount again. Within 24 hours, it had reached $817,000.
A statement from BTS ARMY said: "We stand in solidarity with black ARMY. They're an important part of our family. And we stand with black people everywhere. Your voices deserve to be heard."
Kailee Scales, managing director for Black Lives Matter, told Variety: “Black people all over the world are in pain at this moment from the trauma of centuries of oppression. We are moved by the generosity of BTS and allies all over the world who stand in solidarity in the fight for Black lives.”
The Weeknd is among artists to make a donation to the cause. He donated $500,000 to racial justice initiatives.
