San Francisco: US conspiracy theorist Alex Jones has been suspended from Facebook for bullying and hate speech and is close to having pages tied to him and his Infowars website removed from the platform, the social media network said.

The radio host's personal profile was banned for 30 days after it was found to have uploaded four videos published on pages maintained by Jones and Infowars that went against community standards, Facebook said.

The videos have been removed and Infowars and Jones' pages "are close to being unpublished given recent community standards violations," Facebook said in a statement.

In fact, Jones appeared on a livestreamed Facebook video on his page, shortly after the suspension went into effect, in which he claimed that he was the victim of a media conspiracy to "de-platform" conservative voices.
