Rwandan election-incumbent Paul Kagame expected to win
This is only the second presidential election since the country's genocide in 1994, with five million Rwandans registered to vote. Mr Kagame's supporters say he has brought both stability and steady economic growth, but his critics accuse him of suppressing opposition and undermining democracy.
Mr Kagame won the last election in 2003 with 95% of the vote.
