Activist hackers have taken down Donald Trump's online tower in a "statement against racism and hatred".

The group, Anonymous, announced on Twitter that it had taken down the website for his 68-story Manhattan skyscraper, Trump Towers that he also used for his presidential campaign.

"Trump Towers NY site taken down as statement against racism and hatred.

Earlier this week the group had also posted on YouTube a message urging the mogul to think twice before he spoke.

"Donald Trump think twice before you speak anything. You have been warned Mr Donald Trump."

The activist group's warning followed days after the billionaire proposed to bar Muslims from entering the United States in response to the San Bernardino shooting spree.
