4 years after end of civil war, pressure grows on Sri Lanka government to probe war crimes

The photo shows a boy sitting by a row of sandbags as he glumly eats a snack. The next photo shows him with a series of bullet holes in his chest.

The makers of a documentary on Sri Lanka say the boy was the 12-year-old son of Sri Lankan insurgent leader Velupillai Prabhakaran, and that the photos prove he was executed by the Sri Lankan military. Sri Lanka denies the charge.

The accusation comes as Sri Lanka is struggling to fend off a surge of criticism about its conduct in the final days of the war in 2009 and its treatment of the Tamil minority in the four years since.

Navi Pillay, U.N. High Commissioner for Human Rights, has accused the country of failing to investigate reports of atrocities.
