Sri Lanka's foreign minister Mangala Samaraweera urged UN Secretary General Ban Ki-moon to delay the release of a UN report on alleged war crimes during his country's civil war, a Reuters report said citing UN sources.

In their meeting at UN headquarters in New York, Samaraweera and Ban discussed "critical priorities for Sri Lanka, including especially human rights, accountability and reconciliation," the United Nations press office said in a statement. The UN readout of the meeting said nothing about Colombo's desire for UN High Commissioner for Human Rights Zeid Ra'ad Al Hussein to delay the March 25 release of the war crimes report.

Samaraweera said in Washington earlier this week that the situation at home was fragile and is therefore seeking to delay the scheduled release of the UN Human Rights Council report until "August ... or so."

He raised the issue behind closed doors with Ban on Friday, stressing the importance of a delay, UN diplomatic sources told Reuters on condition of anonymity. For his part Ban, the sources said, made clear this was an issue for Zeid, the Geneva-based UN human rights chief.

Diplomats said that Samaraweera has used his trip to the United States to persuade US and UN officials of the importance of delaying the report.

The UN Human Rights Council voted last March to look into reports of abuses during the civil war that ended in 2009, saying the Sri Lankan government had failed to investigate properly.

Sri Lanka's new government, which took power last month, says it is planning a new domestic inquiry that would bring in some foreign experts if necessary. It has also invited Zeid to visit to discuss the issue.

The issue of the war crimes report is expected to be discussed at a committee meeting of the UN Human Rights Council in Geneva on Monday, when a decision could be taken.
