Commenting on the pictures, military spokesman Brigadier Ruwan Wanigasooriya said, "This is not the first time such unsubstantiated allegations are leveled against the Sri Lankan forces. Interestingly, these come up as we near UNHRC meeting and die down thereafter."
"No substantive evidence have been presented for us to launch an investigation" he said.
"Unfortunately, it appears that the parties who float such baseless allegations never want these to be investigated or solved. They want to keep them as mysteries in order to tarnish the country's good image as and when it suits their agendas."
Wanigasooriya stressed that if the Channel 4 was interested in having these investigated, it should cooperate with credible evidence and the Army will institute a probe.
The documentary aims to test India over its next move in the UNHRC resolution against Sri Lanka, Channel 4's documentary director Callum Macrae said.

"The new evidence in the film is certain to increase pressure on the Indian government not only to support a resolution on Sri Lanka and accountability, but also to ensure that it is robustly worded, and that it outlines an effective plan for international action to end impunity in Sri Lanka," Macrae said.

"The Human Rights Council should dismiss these tactics, end the delays and authorise an independent, international investigation into the estimated 40,000 civilian deaths at the conflict's end," he added.
The HRW statement said that on February 11 this year, the UN Office of
