Some reports say the death toll could be high as 40 but officials have not confirmed this.

Tens of thousands of people had turned up at a stadium in Dar es Salaam to view the body of the former president.

Nicknamed the bulldozer, Mr Magufuli was popular with many Tanzanians for his no-nonsense governance style.

Critics, however, accused him of being an autocrat and of clamping down on dissent.

He died on Wednesday from heart complications at a hospital in Dar es Salaam, Samia Suluhu Hassan said in an address on state television.

Magufuli has not been seen in public for more than two weeks, and rumours have been circulating about his health.

Opposition politicians said earlier this week that he had contracted Covid-19, but this has not been confirmed.

"It is with deep regret that I inform you that today... we lost our brave leader, the president of the Republic of Tanzania, John Pombe Magufuli," Vice-President Hassan said.

The fatal crash happened in city of Arusha in Tanzania's northern Karatu District, on the edge of the Ngorongoro Conservation Area.

"The place where it happened is a hill, with a steep slope, and it was raining when the accident happened," Aruba Police Commander Charles Mkumbo said.

Mkumbo added investigators were still trying to determine exactly what caused the bus to leave the road. "We don't know if the driver was new or if there was a mechanical defect," he said.

The goal is to radically reduce the amount of time it takes to send stock to health clinics in the African nation by road or other means.

The scheme involves Zipline, a Silicon Valley start-up that began running a similar service in Rwanda in October.

Experts praised that initiative but cautioned that "cargo drones" are still of limited use to humanitarian bodies.
