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 captured and then executed by the Sri Lankan military. Sri Lanka denies the charge.
The accusation comes as Sri Lanka struggles to fend off a surge of criticism about its conduct in the final days of the war in 2009 and its treatment of government critics and the Tamil minority in the four years since.
Last week, Navi Pillay, U.N. High Commissioner for Human Rights, accused the country of failing to investigate reports of atrocities and said government opponents were being killed and abducted. The United States has said it will introduce a new resolution on Sri Lanka—urging a full accounting of what happened at the end of the war—when the U.N. Human Rights Council meets next week.
Christian clergy in the country have called for an international inquiry into the final months of the war, and a respected think tank warned the country was growing increasingly autocratic.
The documentary, ''No Fire Zone," which is backed by Britain's Channel 4, Amnesty International and Human Rights Watch among others, is to be shown in Geneva during the sitting of the Human Rights Council.
''The evidence is just mounting," said G. Ananthapadmanabhan, who heads the India chapter of Amnesty International.
Sri Lanka denied the allegations, and said the pictures were fabricated as part of a plot against the country.
"Why did they wait for four years and why did they wait for a Human Rights Council (meeting)?" asked government spokesman Keheliya Rambukwella. "There is a target, the agenda is to tarnish the image of the government. We completely reject the claims."
The director of the film, Callum Macrae, said the timing of the documentary was intended to help inform the debate of the council.
''I'm not going to apologize for that at all. That's not a conspiracy, that's journalism," he said.
The ethnic Tamil rebels and their leader Prabhakaran fought for more than a quarter-century for an independent state in northern and eastern Sri Lanka. A U.N. report says tens of thousands of civilians were killed in the final five months of the fighting.
Prabhakaran pioneered the use of suicide bombing, conscripted child soldiers into his forces and was feared and loathed by the nation's ethnic Sinhalese majority. He was killed at the end of the war in May 2009 along with his oldest son, Charles Anthony.
The documentary shows a series of photos it says depict his youngest son, Balachandran. In the first two, he is sitting by the sandbags, in the third he is apparently dead. Metadata on the photos showed the last one was taken with the same camera, two hours after the first two, the filmmakers said.
Macrae said the photos were authenticated by a forensic pathologist and other experts.
Sri Lankan military spokesman Brig. Ruwan Wanigasuriya said the military was unaware of the fate of Prabhakaran's wife, daughter and youngest son, or if they were even in the country at the end of the war. He questioned the identity of the boy in the photographs.
''How do you know this is Balachandran? Has anyone seen him? Has Mr. Callum Macrae seen him?" he asked.
The film showed an earlier snapshot of the same boy with Prabhakaran and his wife, and MacCrae said his identity was confirmed by people familiar with his image.
Reports of the film's allegations have inflamed anti-Sri Lankan sentiment in the Indian state of Tamil Nadu, whose ethnic Tamils hold deep sympathy for their Sri Lankan brethren.
Chief Minister Jayaram Jayalalithaa backed out this week of hosting the Asian Athletics Championships because of Sri Lanka's participation. ''Tamils will never accept it," she said.
A Tamil Nadu-based government coalition partner, the Dravida Munnetra Kazhagam, called on India to support the upcoming resolution before the Human Rights Council. The government said it needs to see it first.
''As and when this resolution comes into being, we will have a look at it and take a call on it," said Foreign Ministry spokesman Syed Akbaruddin.
Under pressure from the DMK, India, the country with perhaps the most influence over its south Asian neighbor, supported a resolution in the council last year that urged Sri Lanka to investigate human rights abuses and reconcile with its Tamil population.
In a report Wednesday, the International Crisis Group said the government of President Mahinda Rajapaksa had failed to comply with that resolution and instead has worked to centralize power, in part, by impeaching the chief justice. It also lamented the government's abandonment of its pledge to work toward reconciliation after the war. Earlier this month, Rajapaksa ruled out giving Tamil regions greater autonomy, apparently backing away from his repeated promise to do just that.
Christian clergy from the mainly Tamil north also called on the U.N. council to push for an international inquiry to investigate reports of war atrocities.
"We are convinced that the root cause of these problems is a lack of political will," a letter signed by 133 Roman Catholic, Anglican and Methodist clergy members said this week. "Hence, it is our firm conviction that technical assistance from the U.N. in the form of training, advice, financial and material support will not suffice."
