Rwandan President Paul Kagame has won 93% of the vote in the presidential election but his opponents have said the campaign was rife with violence and voter intimidation.

Rwanda's National Electoral Commission said turnout for Monday's election was 97% in all the central African nation's five provinces.
Charles Munyaneza, executive secretary of the electoral body, dismissed the claims of intimidation.
"We can say that we are very happy with the conduct of the electoral process, from the campaign to the voting itself," he said.
"We did not get reports of intimidation from anywhere."
President Kagame has been in control of Rwanda since his rebel army swept to power in the aftermath of the genocide of 800,000 Tutsis and Hutus in 1994.

Mr Kagame's critics have said three opposition presidential candidates were prevented from registering to contest the ballot.
In the run-up to the election a local journalist was shot and killed and an opposition official was killed in July.
Commonwealth observers said the campaign was peaceful and well-managed but had concerns over the pre-election period and the lack of any real critical opposition.
