NAIROBI, Kenya: African Union election observers said late Wednesday that the integrity of Tanzania’s recently concluded elections was “compromised,” citing incidents of “ballot stuffing at several polling stations.”

President Samia Suluhu Hassan won the October 29 poll with 98 percent of the vote, according to the electoral commission, but the opposition, which was barred from participating, branded the election a “sham.”

Violent protests broke out across the country on election day.

The government responded with a total Internet blackout and transport shutdown, and the opposition says hundreds were killed by security forces, though getting verified information remains difficult despite an easing of restrictions.

The AU Election Observation Mission said its observers witnessed voters being issued multiple ballots, with some allowed to cast their votes without their identities being verified against the registry.
