DHAKA, Bangladesh — It was a Pakistani journalist, Anthony Mascarenhas, who gave the world the first detailed account of Bangladesh’s war of independence. In April 1971, soon after the army of Pakistan started suppressing the secessionist movement in what was then still the eastern part of the country, it invited Mr. Mascarenhas to report on the conflict, believing he would buttress the false propaganda of a just war. Mr. Mascarenhas promptly moved his family, and then himself, to Britain knowing that soon he would no longer be able to live in Pakistan.

“For six days as I traveled with the officers of the 9th Division headquarters at Comilla I witnessed at close quarters the extent of the killing,” Mr. Mascarenhas wrote in a lengthy, damning report published under the headline “Genocide” in the June 13, 1971, edition of The Sunday Times.

“I saw Hindus, hunted from village to village and door to door, shot off-hand after a cursory ‘short-arm inspection’ showed they were uncircumcised. I have heard the screams of men bludgeoned to death in the compound of the Circuit House (civil administrative headquarters) in Comilla. I have seen truckloads of other human targets and those who had the humanity to try to help them hauled off ‘for disposal’ under the cover of darkness and curfew.”

Four decades later, Mr. Mascarenhas’s government still insists on denying the past: the mass killing of civilians (perhaps as many as three million), the targeting of Hindus, the systematic rape of thousands. On Dec. 16, Pakistan’s National Assembly adopted a resolution expressing concern over the recent execution of Abdul Quader Mollah, a leader of Jamaat-e-Islami, Bangladesh’s leading Islamic party, who was convicted by a Bangladeshi court of committing murder and rape while collaborating with the Pakistani Army during the 1971 war. Calling Mr. Mollah a Pakistani sympathizer — and the independence of Bangladesh “the fall of Dhaka” — a multiparty majority of the assembly complained that Mr. Mollah was sentenced because of his “loyalty to Pakistan” and asked the Bangladeshi government to drop all other cases against the Jamaat leadership.
