Tanzania's main opposition rejects Hassan's election win after deadly protests

The main opposition party CHADEMA, which was barred from the election for refusing to sign a code of conduct and whose leader Tundu Lissu was arrested for treason in April, said late on Saturday that the results were "completely fabricated".

It added, "CHADEMA strongly rejects the so-called election results announced by the National Electoral Commission. These results have no basis in reality, as the truth is that no genuine election took place in Tanzania," it said on X.

"The countrywide demonstrations are clear proof that citizens did not take part in what is being called an election, and that they reject anyone emerging from this flawed electoral process," the party added in the statement on its account.

There was no immediate reaction from the government to CHADEMA's statement.

Some demonstrators tore down banners of Hassan and set ablaze government buildings while police fired tear gas and gunshots, according to witnesses of the protests that erupted during Wednesday's vote for president and parliament.

OPPOSITION SAYS HUNDREDS KILLED

CHADEMA said on Friday hundreds were killed in the protests, while the U.N. human rights office said credible reports indicated at least 10 deaths in three cities.

Demonstrators are angry about the electoral commission's exclusion of Hassan's two biggest challengers from the race and what human rights groups have said are widespread arrests and abductions of opponents.

The government dismissed the opposition's death toll as "hugely exaggerated" and has rejected criticism of its human rights record. Reuters could not independently verify casualty figures.

In a speech from the administrative capital Dodoma after being certified as the winner, Hassan said the actions of the protesters were "neither responsible nor patriotic".

"When it comes to the security of Tanzania, there is no debate - we must use all available security avenues to ensure the country remains safe," she said.

The authorities have imposed a nationwide curfew since Wednesday and curbed internet access.

Many international flights have been cancelled, and operations disrupted at Dar es Salaam's port, a hub for fuel imports and exports of metals mined across the region.
