Sri Lanka's parliament has rejected an investigation by the United Nations human rights body into alleged crimes during the island nation's civil war that ended five years ago.

Ruling coalition lawmakers overwhelmingly voted Wednesday for a motion that says such a probe "erodes the sovereignty, dignity and statute of Sri Lanka."

The motion was approved by a 144 votes in the 225-member parliament.

The probe by the U.N. High Commissioner for Human Rights comes after a United States-sponsored resolution approved by the U.N. Human Rights Council in May.

The refusal of Sri Lanka's parliament is not binding on the investigation.

Sri Lanka's civil war ended in May 2009. Allegations of serious human rights violations, especially in the final months of the fighting, prompted the U.N. probe.
