PHNOM PENH (REUTERS) - Polls closed in Cambodia's contentious national election yesterday with rights groups saying the vote was neither free nor fair in the absence of any significant challenger to Prime Minister Hun Sen and voter intimidation.
Mr Hun Sen's opponents called for an election boycott.
The National Election Commission (NEC) said in a document sent after polls closed that voter turnout was 70.41 percent nationwide.
But scenes on the ground in the capital Phnom Penh painted a different picture.
At a polling station near the river, election workers outnumbered voters and a slow trickle of people arrived throughout the day.
Another polling station at a school was quiet with a handful of voters casting their ballot in the mid-afternoon heat.
One Dutch tourist visiting Cambodia on holiday said he did not realise it was election day. "Is it election day? I didn't know. Seems very quiet, like a normal Sunday," said the tourist, who declined to be identified to protect his privacy.
Critics say the election is a backward step for democracy in Cambodia, marred by intimidation by the ruling Cambodian People's Party (CPP) and the dissolution last year of the main opposition Cambodian National Rescue Party (CNRP) and the jailing of its leader, Kem Sokha, on treason charges.
Asean Parliamentarians for Human Rights (APHR) said in a statement that the vote took place in a "highly repressive political environment".
Mr Hun Sen, a former Khmer Rouge commander who defected from Pol Pot's murderous regime, has ruled Cambodia for more than 30 years and is the world's longest serving prime minister.
Phil Robertson, deputy director of Human Rights Watch's Asia Division, told Reuters in an e-mail that many voters grudgingly went to the polls out of fear.
Authorities have warned that anyone boycotting the vote will be seen as a "traitor".
One voter at a polling station by the river at Preap Sisowath Quay in Phnom Penh said not voting was "too much trouble". "I did not want to vote but I did vote," said the man, who asked not to be identified.
CPP is banking on a high voter turn-out to bestow a veneer of legitimacy on the election.
Some 8 million people are registered to vote.
Nearly 70 per cent cast their ballot during the last general election in 2013.
Nineteen political parties ran against Mr Hun Sen's ruling CPP, but none are strongly critical of the government.
The opposition CNRP, appealing to younger voters and those seeking change, narrowly lost the last general election in 2013.
The 2018 election is the country's sixth since 1993 when it emerged from decades of war, including the 1975-1979 Khmer Rouge regime which is blamed for the deaths of 1.7 million people.
The National Election Committee will announce preliminary results at around 6 pm local time. Official results are expected in mid-August.
