The programme was organised by the Liberation War Museum on the eve of its 10th anniversary in the city.

Air Vice Marshal (Retd) AK Khandaker presided over the programme at the auditorium of the museum.

Speaking on the occasion Sorya Sim, deputy director of the Documentation Centre of Cambodia, narrated their experience in collecting the documents about the brutal activities of Cambodian war criminals.

Like Bangladesh, around three million people were killed by Khmer Rouge regime in Cambodia in 1970s.

The Documentation Centre of Cambodia popularly known as DC Cam, a non-government organisation, has been collecting the evidences.

On the basis of those evidences the Cambodian government has requested the United Nations to help form a special tribunal to conduct the trial of the war criminals.

"In our field research or publication, we have taken a neutral, objective and transparent approach. Throughout our research, we work without any prejudice, because our job is not to judge but to collect information," said Soriya Sim, also the research director of the DC Cam.

"We have also provided documents requested by the lawyers of the Khemer Rouge regime," he added.

Soriya said with complete neutrality, they have interviewed 500 former Khmer Rouge cadres and 2000 non-cadres.

While describing the effectiveness of their documents, he said DC Cam documents are assessed as 'excellent' by the UN groups of Experts.

Dr Sarowar Ali and Mofidul Haq, trustee members of the Liberation War Museum, also spoke at the programme.
