DHAKA A Bangladesh war crimes tribunal sentenced a senior leader of the country's biggest Islamist party to life in prison on Tuesday, the second verdict in trials that have reopened wounds about the country's independence war and sparked riots.
Abdul Quader Mollah was found guilty of charges including murder, rape, torture and arson during Bangladesh's war to break away from Pakistan in 1971.
Activists of Mollah's Jamaat-e-Islami party clashed with police in the capital, Dhaka, and other towns after the verdict and one person was killed in the eastern city of Chittagong, police and witnesses said.
The court delivered its first verdict last month, sentencing a former member of Jamaat-e-Islami and popular Islamic preacher to death, and a state prosecutor said he had been expecting the same sentence on Tuesday.
"We are not happy with the verdict and the merit of the judgement is not clear to us," said Mohammad Ali, a state prosecutor. "We wanted his death and are surprised by the lesser punishment handed out by the tribunal."
Quader Mollah made a "V" for victory sign while getting into a car after the verdict.
Bangladesh became part of Pakistan at the end of British rule in 1947 but it broke away in 1971 after a war between Bangladeshi nationalists, who were backed by India, and Pakistani forces.
Some factions in Bangladesh opposed the break with Pakistan and numerous abuses were committed during the nine-month war.
The Jamaat-e-Islami has vowed to paralyse the country in protest against a tribunal that it says is politically biased. Shops and businesses were shut and the streets were mostly empty in the capital as the Jamaat-e-Islami enforced a national strike against the verdict.
Hundreds of war veterans thronged outside the Dhaka court as the verdict was delivered, demanding that Mollah be put to death. There was tight security around the court premises, prompted by fears of a possible attack by Islamist militants.
Another 10 people are awaiting trial by the tribunal.
Prime Minister Sheikh Hasina set up the tribunal in 2010 to investigate abuses during the conflict that claimed about 3 million lives and during which thousands of women were raped.
But critics say the prime minister is using the tribunal against members of the two biggest opposition parties, the Bangladesh Nationalist Party (BNP) and the Jamaat-e-Islami.
Begum Khaleda Zia, Hasina's arch rival and leader of the BNP, has called the tribunal a "farce".
The ruling party has rejected accusations that the tribunal is biased but it has been criticised by human rights groups for failing to adhere to standards of international law.
Five people have been killed in recent weeks in violence related to the trials. About 150 people have been injured and a similar number arrested, police have said.
Jamaat activists are demanding that the government dissolves the tribunal and releases all of its leaders facing trial, who include the party's former and current chiefs, Golam Azam and Motiur Rahman Nizami, and their top lieutenants.
The party has been accused of opposing the campaign for independence from Pakistan and helping the Pakistani army during the war in what was then East Pakistan.
Jamaat denies that.
