DHAKA (Reuters) - Bangladesh hanged Islamist party leader Motiur Rahman Nizami on Wednesday for genocide and other crimes committed during the 1971 war of independence from Pakistan, the law minister said, risking an angry reaction from his supporters.
Nizami, head of the Jamaat-e-Islami party, was hanged at Dhaka Central jail just after midnight, Law Minister Anisul Haq told Reuters, after the Supreme Court rejected his final plea against a death sentence imposed by a special tribunal for genocide, rape and orchestrating the massacre of top intellectuals during the war.
Nizami, 73, a former legislator and minister during opposition leader Khaleda Zia's last term as prime minister, was sentenced to death in 2014.
Hundreds of people flooded the streets of the capital, Dhaka, to cheer the execution. "We have waited for this day for a long 45 years," said war veteran Akram Hossain. "Justice has finally been served."
But the war crimes tribunal set up by Prime Minister Sheikh Hasina in 2010 has sparked violence and drawn criticism from opposition politicians, including leaders of Jamaat-e-Islami, that it is victimizing Hasina's political opponents.
Thousands of extra police and border guards were deployed in Dhaka and other major cities. Previous similar judgments and executions have triggered violence that killed around 200 people, mainly Jamaat activists and police.
Five opposition politicians, including four Jamaat-e-Islami leaders, have been executed since late 2013 after being convicted by the tribunal.
Jamaat-e-Islami, which has said the charges against Nizami were baseless, called for a nationwide strike on Wednesday in protest. Calling Nizami a 'martyr', it said he was deprived of justice and made a victim of a political vendetta.
The U.S. State Department said that while it supported justice being carried out for the 1971 atrocities, it was vital that the trials of those accused are free, fair and transparent and conducted in accordance with international agreements.
"While we have seen limited progress in some cases, we still believe that further improvements to the ... process could ensure these proceedings meet domestic and international obligations," State Department spokeswoman Elizabeth Trudeau said in a statement. "Until these obligations can be consistently met, we have concerns about proceeding with executions."
About three million people were killed, the government says, and thousands of women were raped during the 1971 war in which some factions, including the Jamaat-e-Islami, opposed the break from what was then called West Pakistan.
The party denies that its leaders committed any atrocities.
International human rights groups say the tribunal's procedures fall short of international standards. The government denies the accusations.
The execution comes as the Muslim-majority nation suffers a surge in militant violence in which atheist bloggers, academics, religious minorities and foreign aid workers have been killed.
In April alone, five people, including a university teacher, two gay activists and a Hindu, were hacked to death by suspected Islamist militants.
International human rights groups say a climate of intolerance in Bangladeshi politics has both motivated and provided cover for perpetrators of crimes of religious hatred.
