The DMK on Friday threatened to quit the UPA government unless the U.S.-sponsored resolution on Sri Lanka in the United Nations Human Rights Council was strengthened with a firm demand for an independent international probe into war crimes.

“If this demand is not conceded, I categorically state our continuation in the ministry will be meaningless,” party president M. Karunanidhi said in a statement.

He said the resolution should reflect the demand for an inquiry into the alleged genocide, identification of war criminals and an independent probe.

“India should take steps to get these amendments included in an unequivocal manner in the draft resolution prepared by the U.S. and take action within a time frame,” Mr Karunanidhi said.
