Twitter's new owner Elon Musk says Donald Trump's account has been reinstated after running a poll in which users narrowly backed the move.
Twitter's previous management acted just days after Donald Trump's supporters stormed the US Capitol in Washington DC on 6 January.
Hundreds of rioters entered the complex as the US Congress attempted to certify Joe Biden's victory in the presidential election. The ensuing violence led to the deaths of four civilians and a police officer.
Earlier this week, the Republican announced that he would once again run for the US presidency in 2024.
