Seven of the convicts were brought from the prison to hear the verdict. Six others were sentenced in absentia as they are on the run. Arrest warrants have been issued for the six.
“They are found guilty of treason conspiracy by forming illegal armed forces under the name of the Khmer National Salvation Front with an aim to topple the government,” Xinhua reported citing the Phnom Penh Municipal Court verdict.
Sam Serei, a mastermind of the movement, was sentenced to nine years in jail in absentia as he has fled the country.
The group had carried out hostile acts against Cambodia between 2009 and 2011.
The seven men were arrested in March last year in Thailand’s Pathum Thani province.
