Social networking giant Meta announced Tuesday that it would soon reinstate former US president Donald Trump's accounts on Facebook and Instagram with "new guardrails," two years after he was banned over the 2021 assault on the Capitol.

"We will be reinstating Mr. Trump's Facebook and Instagram accounts in the coming weeks," said a statement by Nick Clegg, Meta's president of global affairs.

It was not clear when or if Trump, who has already announced a third White House bid, will return to the platforms, and his representatives did not immediately respond to a request for comment.

Facebook banned Trump a day after the January 6, 2021 insurrection, when a mob of his supporters tried to halt the certification of his election defeat to Joe Biden by storming the US Capitol in Washington.
