Tanzania opposition leader Tundu Lissu is accusing the government of using dirty tricks to curtail his campaigns just three weeks to the general election.
Speaking to Reuters Lissu said that the current regime was "using every instrument of power in their capacity, in their possession to thwart my election campaign."
Lissu, from the main opposition Chadema party, says the party offices in Arusha, northern Tanzania were firebombed.
Meanwhile, dozens of opposition parliamentary candidates were disqualified from running in the elections for president and members of parliament, which take place on Oct. 28.
President John Magufuli is widely expected to win a second term and his government has previously denied clamping down on dissent.
Lissu returned in July after three years in exile following an unsolved 2017 assassination attempt in which he was shot 16 times.
