The UN High Commissioner for Human Rights, Zeid Ra'ad al Hussain, will visit Sri Lanka in June, according to Foreign Minister Mangala Samaraweera.
Speaking in parliament on Wednesday, the minister said Mr Hussain's visit was in line with the UN's focus on Sri Lanka, the Daily Mirror reported.
“Failure to carry out a domestic investigation will lead to an international investigation which might in turn lead to foreign intervention,” the minister said.
“One must not treat the upholding of human rights as a western value. It should be treated as a universal value,” he added.
