Coimbatore, Sep 05 (ANI): General Secretary of MDMK, Vaiko urged the United Nations to withdraw Sri Lankan President Mahinda Rajapaksa's invitation to deliver his address at the General Assembly. Referring to the alleged war crimes committed by Sri Lankan army during the civil war that ended in 2009, Vaiko said that Rajapaksa has committed the inferable crime of genocide of Tamil, and that he should be tried by the international court. An independent international investigation, he added, has been ordered by Human rights Commissioner, but Rajapaksa has the audacity to say that he will not permit the investigation team to enter Sri Lanka.
