The site's popularity soared in recent weeks, becoming the number one free app in Apple's App Store after the much larger Twitter banned US President Trump from its platform for his role in inciting a riot at the US Capitol last week.

Messages of support for Wednesday's attack in Washington DC -- along with calls for new demonstrations -- had flourished on the platform, leading Google to remove it from its app store on Friday, followed by Apple on Saturday.

Amazon then confirmed it would suspend the platform from its cloud hosting services for allowing "threats of violence."

In a letter to the Parler's owners, the web giant said it would suspend service by 11:59 PM on Sunday (0759 GMT Monday).
