A senior US official called for Sri Lanka to implement a "credible domestic" mechanism with "substantial involvement" from the international community.

US assistant secretary of state for South and Central Asian affairs Nisha Biswal told PTI that the Sri Lankan government had demonstrated "a very strong intent" in addressing rights concerns.

The Northern Province's Chief Minister CV Wigneswaran said Sri Lanka does not have judges or prosecutors to deal with war crimes cases.

Speaking after the release of the UN's report calling for a hybrid mechanism with international judges, Mr Wigneswaran, a former supreme court judge himself, said there was no judge in Sri Lanka who would find fault with the military.

The chief minister welcomed the OHCHR report and said he was happy it called for international participation.

Mr Wigneswaran also welcomed the resolution passed in Tamil Nadu's assembly, which called for an international inquiry.

The hybrid mechanism recommended by the UN's human rights office will not be effective in delivering accountability, the International Centre for Prevention and Prosecution of Genocide said in a statement.

The London-based organisation welcomed the OHCHR's report, which detailed serious allegations of mass atrocities committed during the armed conflict in Sri Lanka, but said the premise for a hybrid mechanism is flawed.

Commending the "admirable thoroughness" of the report, the ICPPG said a mechanism ensuring accountability must now be instituted.

"The Sri Lankan Government’s proposal of a domestic tribunal or as an offer of compromise to the international community, a hybrid tribunal, will not secure the aims that the Human Rights Commissioner has stated," the statement said.

"The Report itself speaks about the pressures that Sri Lankan judges are subject to. Such pressures will continue if domestic judges are appointed to a hybrid tribunal. The experience of the hybrid tribunal in Cambodia is a case in point. In situations where the alleged perpetrators still enjoy power within the Sri Lankan society, the possibility of such pressure is indeed certain,

Speaking at the inauguration of the first Jaffna International Film Festival, Chief Minister CV Wigneswaran highlighted the deade-long ongoing discrimination against the Tamil people by the state.

See below for excerpts of his speech:

"The cinematic art could be used to bring communities together or to divide and destroy communities. Let us make up our minds to mend fences that have kept our communities apart from each other. While doing so let us be aware of the power of the cinematic art to subtly condition the minds of our people in such a way as to deviate them from their desired goals.

"The Tamil community has been discriminated against continuously since Independence. I was fortunate enough to have lived during my early childhood in many parts of this Country as a citizen of the Great British Empire which ruled us then before independence. My early education was in Kurunegala and Anuradhapura before I joined Royal Primary in Colombo. My father was also stationed in Kandy and Tangalle as a Government Officer. As an original Court Judge later I had functioned in different parts of this Country. The significant thing I have noticed is that the camaraderie, the good will and wellbeing, the brotherly and humane relationship that existed prior to independence in this country is lacking now. Tamil speaking people who used to live and own lands and do businesses in many parts of the South had been driven out from their residences by pogroms and riots,

The SLFP said it will protect those who dedicated their services to safeguard the sovereignty of the country, according to general secretary Duminda Dissanayake.

Mr Dissanayake said the party had set up a committee to look at the document released by the UN's human rights office on Wednesday and that its response to the recommendations will be announced once the committee had studied and submitted a report on it.
