Prime Minister Mwigulu Nchemba has said. His announcement comes as the opposition and others have been calling for people to gather on independence day - 9 December - to demonstrate about killings that took place following last month's disputed poll. The opposition believes hundreds of people died in the crackdown. The government has yet to give a death toll and has set up commission of inquiry. President Samia Suluhu Hassan won the poll with 98% of the vote, described by the opposition as a "mockery of democracy".

Her key opponents were unable to contest the poll: Tundu Lissu has been in detention on treason charges, which he denies, while Luhaga Mpina's candidacy was rejected on technical grounds. Election observers have since reported signs that the vote was manipulated and fell short of democratic standards. The government had imposed an internet blackout for five days from the 29 October election day and threatened anyone sharing photos from the protests. (BBC)
