Sri Lanka has sought two more years from the UN Human Rights Council to probe the alleged war crimes committed during the conflict with the LTTE. <br/><br/>The foreign ministry said in Colombo yesterday it has sought more time to deliver on accountability mechanism at the current 34th session of the UNHRC. Sri Lanka was granted 18 months by a UNHRC resolution in October 2015 to initiate a credible investigation into the nearly three-decades long civil war with the LTTE. <br/><br/>According to the UN figures, up to 40,000 civilians were killed by the security forces during former president Mahinda Rajapaksa's regime that brought an end to the conflict with the defeat of LTTE in 2009. Earlier this month, the UNHRC had criticised Sri Lanka's "slow" progress in addressing its wartime past and reiterated its earlier call for hybrid court of international and local judges to investigate allegations of rights violations.
