The International Labour Organization (ILO) has joined calls for an end to continuing violence in Cambodia, saying it is "deeply disturbed" by reports of another crackdown on protesting workers.

At least eight people were injured at a rally on Sunday (26 January), which was organised by nine unions and associations calling for the release of 23 workers arrested during strike action earlier this month.

Their detention was linked to industrial unrest over disputed minimum wage increases and claims of harassment and violence against defenders of human rights.

The ILO said it urges all parties to "refrain from further violence, and to take all steps necessary for the release of the trade union leaders and workers detained for having participated in the strike over the minimum wage."

The body also reiterated its earlier call for the Government to launch an independent inquiry to determine the circumstances of police action and the deaths, assaults and arrests of workers during strike action earlier this month.

"The inquiry should determine responsibilities and punish those responsible where appropriate, as well as outline the steps to prevent the repetition of such acts," it said.

Four demonstrators were killed in clashes between armed police and protestors in early January after garment workers went on strike as part of the minimum wage dispute.
