Sri Lanka: UN says shelling killed civilians

The UN has said widespread shelling by the Sri Lankan government killed most of the tens of thousands of civilians who died in the final months of the 25-year war, in 2009.

The report also accuses Tamil Tigers separatists of using civilians as human shields.

The UN is calling for an independent investigation into what it says could constitute war crimes.
