Bangladesh has hanged opposition leader Abdul Quader Mollah over war crimes, making him the first person to be put to death for massacres committed during the country's bloody 1971 war of independence.
Abdul Quader Mollah, 65, a senior leader of the Jamaat-e-Islami (JI) party, was hanged on Thursday at 10.01pm (16:01 GMT) in a jail in the capital, Dhaka, government officials said.
The legal case against Mollah has heightened political tension in Bangladesh less than a month before elections are due. Jamaat-e-Islami is barred from contesting elections but plays a key role in the opposition movement led by the Bangladesh Nationalist Party (BNP).
Security was tight around the jail where Mollah was hanged. Extra police and paramilitary guards were deployed on the streets of Dhaka, while hundreds of people gathered at a major intersection in the city to celebrate the execution.
Moqbul Ahmed, JI's acting leader, said in a statement on the party's website that people would revenge Mollah's execution by deepening the role of Islam in Bangladesh. The party called a nationwide general strike for Sunday.
Micro-level civil war
Al Jazeera's Tanvir Chowdhury, reporting from Dhaka, said that judges' ancestral homes had been attacked in the wake of the decision.
"It has been a very tense atmosphere in which this review is going on," our correspondent said.
The country is on a razor's edge... with pre-election tensions running high and almost non-stop street protests.
"People are worried, it's almost like a micro-level civil war."
While a strong reaction to the decision from JI was expected on the streets of Dhaka, the city remained relatively calm.
But at least five people were killed earlier on Thursday near the port city of Chittagong as clashes broke out between opposition activists and police.
Party activists also clashed with police, torched or smashed vehicles, and set off homemade bombs in the cities of Sylhet and Rajshahi, TV stations reported.
Scores of people were injured in the latest violence to hit the South Asian country, which has seen weeks of escalating tension as it struggles to overcome extreme poverty and rancorous politics.
In eastern Bangladesh, security officials opened fire to disperse opposition activists, leaving at least three people dead and 15 others wounded, Dhaka's leading Bengali-language newspaper, Prothom Alo, reported.
The violence broke out in Laxmipur district, 95km east of Dhaka, during a nationwide opposition blockade after elite security forces raided and searched the home of an opposition leader, the report said.
Life sentence overturned
The Supreme Court passed the order of a review petition filed by Mollah against its verdict, awarding him the death penalty for his wartime offences. He had originally been due to be hanged on Tuesday, his lawyer said, but the court delayed the execution to consider his petition.
His original life sentence had been overturned by the Supreme Court in September, after mass protests called for him to be hanged.
A panel of five judges led by Chief Justice Mohammad Mojammel Hossain rejected the petition after hearing arguments on the appeal against the death penalty, a state prosecutor said.
Mollah is one of five opposition leaders condemned to death by Bangladesh's International Crimes Tribunal (ICT), set up in 2010 to investigate atrocities perpetrated during the 1971 conflict, in which three million people died.
Critics of the tribunal say it has been used as a political tool by Prime Minister Sheikh Hasina, who is locked in a political feud with BNP leader Begum Khaleda Zia, as a way of weakening the opposition ahead of January 5 elections.
"The execution of... Mollah should never have happened," said Abbas Faiz, Amnesty International's Bangladesh researcher. "The country is on a razor's edge... with pre-election tensions running high and almost non-stop street protests."
But many Bangladeshis support the court, believing that those convicted of war crimes should be punished, underlining how the events of 42 years ago still resonate in the impoverished, divided nation of 160 million people.
