Sri Lankan police officials have reportedly attempted to stop a signature campaign in Jaffna calling for an international accountability mechanism to examine mass atrocities committed during the final stages of Sri Lanka's armed conflict, where tens of thousands of Tamil civilians were killed. The campaign, launched yesterday, had entered its second day and was taking place in locations across the North. In Nallur, whilst temple festivities were taking place campaigners set up a stall and collected signatures from the Jaffna public. The president of the Tamil National People's Front Gajendrakumar Ponnambalam tweeted that Nallur police officials had subsequently arrived as signatures were being gathered and "ordered it to be stopped". Speaking to the Tamil Guardian, Mr Ponnambalam said that despite permisssion being granted by Jaffna municipal authorities, police officers led by IC Yapa of Nallur police station demanded the campaigners stop collecting signatures and relocate. The campaign, organised by the Tamil Action Committee for International Accountability Mechanism (TACIAM), is collecting signatures ahead of the United Nation Human Rights Council session later this month, where a report into mass atrocities in Sri Lanka is to be discused. Tens of thousands have signed the petition since the campaign was started. - Sri Lankan police today disrupted a signature campaign in Trincomalee, calling for an international accountability mechanism to deal with mass atrocities committed during the final stages of Sri Lanka's armed ethnic conflict. The organisers of the campaign were asked by police to meet the chief inspector over a complaint that they were forcibly recruiting signatures in Trincomalee. President of the Tamil National People's Front Gajen Ponnambalam, who went to the police station, tweeted that the campaign was filmed by the police media unit, pointing out that the police could confirm that the allegations were untrue by checking their footage. Mr Ponnambalam further said that he was told the campaign was illegal as it was "against the government". The campaign, which was launched on Friday in Jaffna, entered its 4th day today. Sri Lankan police officials in Jaffna also attempted to stop the campaign on Saturday.
