HARARE, Zimbabwe (AP) — President Robert Mugabe has been sworn in for a sixth term, just hours after electoral officials said he won a discredited runoff.

As dignitaries watched under a red-carpeted tent on Sunday, Mugabe swore to uphold his nation's laws and then sat amid cheering to sign documents.

African and other world leaders had condemned Friday's presidential runoff, in which Mugabe was the only candidate.

Human rights groups say opposition supporters were the targets of brutal state-sponsored violence during the campaign, leaving more than 80 dead and forcing some 200,000 to flee their homes.

Opposition candidate Morgan Tsvangirai withdrew from the race because of the violence.
