Tanzania's information ministry on Thursday imposed a two-year suspension on the Mawio weekly, a frequent critic of the government, after it linked former presidents Jakaya Kikwete and Benjamin Mkapa to dubious mining contracts.
A recent investigation into the mining deals, ordered by current President John Magufuli, estimated that 75 billion euros (USD 84 billion) had been lost in tax evasion arising from mining operations since 1998, but did not mention the former heads of state.
Simon Mkina, editor-in-chief of the suspended publication, told AFP he has received threatening, anonymous phone calls in the days since the suspension.
"After the newspaper's suspension, I have received three phone calls threatening me," he said in a telephone interview this weekend.

"One of them, a male voice, asked me if I attached any value to my life. I asked him who he was but he cut off.
Mkina said he has informed both the board of the newspaper and the police who told him it would be difficult to act as they were anonymous calls.
The government panel found that the losses were primarily due to the failure of foreign companies operating in Africa's fourth largest gold producer to declare earnings. It blamed flawed contracts unfavourable to the state.
Magufuli accused Canadian mining giant Barrick Gold of "stealing from us" in a live televised address this week, but welcomed discussions when the firm's CEO John Thornton flew to Tanzania last week.
Despite alleging threats, Mkina said he plans to go to court to challenge his newspaper's suspension.
"We are just negotiating with a good lawyer. We should get to court next week," he said.
