Tamil Nadu Chief Minister J Jayalalithaa and parties across the state have criticised the United Nations Human Rights Council on Sri Lanka as “weak” and that it will not lead to justice for those that were killed by Sri Lankan security forces.

"The resolution passed yesterday will in no way render justice to Sri Lankan Tamils. This resolution is in favour of Sri Lankan government and adversarial to Sri Lankan Tamils," said Ms Jayalalithaa in a statement. "This weak resolution adopted by perceiving a change of heart of the Srilankan government will not do any good to Srilankan Tamils," she added.

She went on to express his disappointment at the Indian central government for not acting on the Tamil Nadu Assembly resolution passed last month calling on the Indian central government to back an international investigation into the mass atrocities. “I had clearly stated in the Tamil Nadu Assembly that the Indian government had the duty to prevent a resolution asking Sri Lanka itself to probe into war crimes … However, that the Central government has not taken any positive steps over this issue has caused unhealable wound," she said.

Sri Lanka’s former president Mahinda Rajapaksa said it was the duty of the government to look after “the interests of our war heroes” in a statement criticising the response to a UN Human Rights Council resolution passed last week.

A Sri Lankan navy officer and former police constable have been taken into custody over the murder of Tamil National Alliance MP Nadaraja Raviraj in 2006, reports The Sunday Leader.

A Navy Petty Officer identified as Senevi and a former police constable named Manamperi were reportedly arrested by Sri Lanka’s Criminal Investigations Department (CID), accused of carrying out the assassination.

The Sunday Leader also reported that the weapon used to gun down the parliamentarian, was reportedly given to paramilitary leader Pillaiyan by Sri Lankan Colonel Shammi Karunaratne, who is currently being detained over the disappearance of journalist Prageeth Eknaligoda.

Canadian Tamil Congress welcoming the UNHRC resolution on the findings of the UN report into Sri Lanka’s atrocities noted that “a significant” amount of work still remained to be done to “earn the trust and support of the Tamil community.”

“While CTC acknowledges that this resolution is an important step in the right direction, we know there remains significant work to be done to ensure that the ensuing processes earn the trust and support of Tamil victims and war-affected communities.”

CTC went on to call for any accountability mechanism to involve international judges, investigators and prosecutors whilst highlighting the need for full consultation fo victims and confidence building measures.

The JVP says the UNHRC's resolution, calling on Sri Lanka to implement a credible justice mechanism to account for mass atrocities, poses some dangers to the country.

The party's secretary general, Tilvin Silva, said to reporters that several of the proposals in the resolution, including the call for international involvement cannot be accepted and could be a tactic by the West and the US to interfere in Sri Lanka.
