"Dear Secretary of State Clinton,
We are writing in advance of your meeting with the Sri Lankan Minister of External Affairs, GL Peiris, to encourage strong US action to end impunity for war crimes in Sri Lanka.
One year after the end of the armed conflict, Sri Lanka has failed to undertake any meaningful steps to investigate serious allegations of laws-of-war violations, despite repeated calls from the international community to do so. A commission of inquiry that Sri Lankan President Mahinda Rajapaksa created on May 15, 2010, the Lessons Learnt and Reconciliation Commission (LLRC), is not empowered to investigate such allegations and seems designed to deflect international criticism rather than to uncover facts and ensure accountability."
