A US judge, ruled she ‘must dismiss’ a suit against the Sri Lankan President over allegations of killings by his country’s armed forces as the American administration has decided that he is immune from litigation as a foreign head of state.

"The court does not take this step lightly," U.S. District Judge Colleen Kollar-Kotelly wrote in her ruling dismissing the case against President Mahinda Rajapaksa.

The International Crisis Group (ICG) warned that the current ground situation in Sri Lanka could result in "future violence", and the UN Human Rights Council had a chance to do something about that.

The online site, Tamilnet, was out of service at the weekend after experiencing effective cyber-attacks, ahead of the 19th UN Human Rights Council session.

In a statement, published Monday, Tamilnet's editorial board, said,

"Distributed Denial of Service Attack (DDoS), identified by the service provider of TamilNet as originating from specific parts of the world, has been disrupting web traffic of TamilNet.com since Saturday."

“Americans, if you want to die like dogs as Prabhakaran did, come to Sri Lanka.”

Human Rights Watch (HRW) produced fresh evidence of Sri Lanka’s torture of recent Tamil deportees, on Friday, which significantly bolsters ongoing litigation to halt the UK’s continuing deportations says Tamils Against Genocide (TAG) in a litigation update released Saturday.

Spokesperson from TAG, Jan Jananayagam said,

Sri Lanka's delegation to the UN Human Rights Council in Geneva due to begin Monday, assured the UN High Commissioner for Human Rights, Navi Pillay, that "we [Sri Lanka] have dealt with accountability isses".

Speaking to reporters afterwards, Sri Lanka's irrigation minister, Nimal Siripala de Silva, said when Pillay has raises the issue of war crimes and the UN expert panel report, they responsed promptly.

“We corrected her immediately. We have dealt with accountability issues.”

Sri Lanka has expressed outrage at the humiliating treatment meted out to Major General Shavendra Silva by a UN committee.

Silva, who is accused of war crimes, was ejected from the peacekeeping advisory panel to Bank Ki-moon earlier this week, after widespread criticism of his selection to the committee.

"To seek to exclude him from a position in the UN is unfair and contrary to the principles of the United Nations," the Sri Lankan government said in a statement issued in New York.
