People in DR Congo are voting in a presidential run-off many hope will help bring stability to central Africa.
Voters are choosing between incumbent Joseph Kabila and his bitter rival, businessman Jean-Pierre Bemba.
Polling has generally been peaceful but Mr Bemba's supporters have burnt ballot papers in the north-eastern town of Bumba, after claims of rigging.
Heavy rainfall in Kinshasa meant some polling stations stayed open into the evening.
Years of conflict and mismanagement have devastated DR Congo's infrastructure, such as this polling station.
Mr Kabila is favourite to win, and enjoys considerable support in the east of the country.
Mr Bemba, a former rebel leader, enjoys strong backing in the capital, Kinshasa.
The vote count began on Sunday evening but results are not expected for a week.
The United Nations - which has a large peacekeeping force in DR Congo - hopes the vote will provide a boost to other poor African countries.
