ACCRA, Ghana (AP) — President John Dramani Mahama on Sunday was declared the winner of Ghana’s presidential election, despite widespread technical glitches with the machines used to identify voters and protests by the country’s opposition which claims the vote was rigged.

Armored tanks surrounded Ghana’s electoral commission and police barricaded the road around the electoral offices as the election body’s chairman Kwadwo Afari-Gyan announced that Mahama had polled 5.5 million votes, or 50.7 percent.
