US rapper Juice Wrld has died after suffering a seizure while walking through Chicago's Midway airport.

TMZ reported that Juice Wrld, real name Jarad Anthony Higgins, had just landed and was walking through the airport when he collapsed and was bleeding from the mouth when paramedics arrived.

He was still conscious when he was taken to hospital but died a short time later.

He was 21.

The rapper had his first hit in 2018 with Lucid Dreams and later signed a multi-million dollar record contract.
