Grime artist Wiley has been permanently banned from Twitter, five days after posting anti-Semitic remarks.

Axar.az reports citing foreign media.

It follows a 48-hour boycott of Twitter by many users over what they said had been an unacceptable delay in dealing with the offending tweets.

"We are sorry we did not move faster," Twitter said in a statement.

The escalation comes a day after Facebook and Instagram deleted the music star's accounts for "repeated violations" of their rules.

Twitter said it has taken a similar step because the artist had broken its "hateful conduct" policy.
