UN report criticises 2009 Sri Lanka 'war crimes'

Tens of thousands of civilians died in the final phase of Sri Lanka's civil war - most of them killed in shelling by government forces, according to a UN panel.

In a report on possible war crimes in the last months of the war in 2009, the panel also says Tamil Tiger rebels used civilians as human shields.

It wants an independent international investigation into "credible" reports of atrocities committed on both sides.
