Tanzania’s opposition Chadema party office in the north-eastern town of Arusha has been “firebombed”, according to its leader Tundu Lissu.
Mr Lissu said the office was destroyed on the eve of his visit to the town on Friday.
He has termed the act as “terror and intimidation”.
The politician said his planned visit would still go on despite the attack.
Mr Lissu returned to Tanzania last month after surviving an assassination attempt in 2017 that saw him seek treatment in Kenya and Belgium.
Mr Lissu has been nominated by his party to run for the presidency in October’s general elections, but has said he lacks confidence in the electoral commission.
