People of the Democratic Republic of Congo have been voting in their first chance freely to elect a president in more than 40 years.
The presidential run-off is intended to end decades of war and pillage that have left the country devastated, despite its mineral riches.
However, voters also faced driving rain and fears raised by campaign violence.
More than 25 million Congolese were registered to choose between incumbent President Joseph Kabila, who took a lead in July's first round, and Jean-Pierre Bemba.
Mr Bemba is a businessman and former rebel who became a vice-president during a three-year transition from war to a democratic process.
There are reports that police have killed two rioters in the town of Bumba, 800km from Kinshasa when supporters of presidential candidate Jean-Pierre Bemba destroyed a polling station after alleging a ballot box had been stuffed with votes for his opponent, the incumbent president, Joseph Kabila.
Both candidates have said they will accept the result.
The polls were to close at 4pm Irish time.
The election is the final step in a peace process after five years of the bloodiest conflict since WWII.
More than four million people died in the humanitarian catastrophe caused by the war, which ended in 2003, and 1,200 still perish every day.
