The Fortnite publisher announced on 21 March it would donate all proceeds from in-game sales, including cosmetic in-game items and virtual currency bought in a shop or online, until 3 April.

Xbox is donating the fee it would usually take on items bought by players in Fortnite.

The amount raised so far is greater than that given by some countries.

A statement on the Fortnite website said it would send funds "as quickly as we can".
