Hundreds of people are lining up in Guinea to begin voting in the country's second democratic presidential election in more than half a century.

Six million Guineans are expected to vote Sunday at more than 14,800 polling stations under surveillance of anti-riot police, gendarmerie and international observers.

President Alpha Conde is running against seven candidates, including main opposition leader, Cellou Dalein Diallo. Conde defeated Diallo in a 2010 election marked by clashes between their supporters along ethnic lines. Similar clashes this week killed at least three people and injured some 50.

Guinea endured decades of corrupt dictatorship after its independence from France in 1958.

Many analysts believe the vote will eventually head to a second round that could see Conde face off against Diallo yet again.
