The United States has warned Sri Lanka over its attempts to silence those who cooperate with the UN on the OHCHR Investigation in Sri Lanka (OISL).

The US Ambassador to the UN Human Rights Council Keith Harper said in a tweet that attempts at intimidation to those individuals were an attack on the UN.

Sri Lanka has warned against submitting evidence to the OISL and has arrested one individual who was collecting information for submission to the inquiry.

An Indian tribunal at the high court in Delhi, looking into the ban on the Liberation Tigers of Tamil Eelam, heard that the organisation continued to be active in a manner detrimental to India, reported PTI.

Abeywardena made the claim at the ruling Sri Lanka Freedom Party headquarters on Wednesday. ColomboPage reported the minister as saying “The opposition is breaking into pieces and the government is getting stronger.”

Sri Lanka’s Minister of External Affairs GL Peiris expressed his “deepest displeasure” at recent comments by a spokesperson for the Office of the High Commissioner for Human Rights, who said that submissions of evidence to the OHCHR Investigation in Sri Lanka, which are received after the deadline, will not necessarily be refused.

During a meeting with the heads of missions and representatives of the main countries involved in the OISL, including the High Commissioner of Australia and the deputy country director of the UNDP, Peiris “expressed strong displeasure at the selective and biased approach followed where the investigation determines the nature of the information they wish to receive”, an MEA statement said.

The Deputy Labour Minister Sarath Weerasekara has called for the Tamil National Alliance (TNA) to be banned.

The Sri Lankan government has rejected a demand reportedly made by the Sri Lanka Muslim Congress, to establish separate administrative districts for Muslims, after UNP MP Wijeyadasa Rajapakshe raised the issue  in parliament, criticising the proposal as unethical.

"This is a dangerous trend in politics. All of us must oppose the SLMC’s move. The government has the wherewithal to act against such projects," Rajapakshe said.
