A tribunal in Bangladesh has sentenced Islamist leader Delwar Hossain Sayeedi to death for crimes committed during the country's 1971 war of independence.

Recent weeks have seen a series of angry demonstrations demanding the execution of Jamaat leaders being tried by the tribunal. But there have also been protests against the court.
Several people have been killed during violent clashes over the issue around the country.
The verdict is the third issued by the controversial tribunal, which is trying a total of nine Jamaat leaders and two members of the Bangladesh Nationalist Party.
Sayeedi was accused of working with the Al-Badr group during the independence struggle and carrying out numerous atrocities, including forcibly converting Hindus to Islam.
His critics say that during the war he formed a small group to loot and seize the property of Bengali Hindus and those who supported independence.
The tribunal found Sayeedi guilty of eight out of the 20 charges levelled against him. These were mass murder, torture, rape and forcibly converting Hindus to Islam.
State prosecutor Syed Haider Ali described the verdict as a "victory for the people", AFP reports. But in court Mr Sayeedi protested, blaming the judgement on the influence of bloggers and pro-government forces.
Earlier this month another Jamaat leader, Abdul Kader Mullah, was sentenced to life for crimes against humanity. Huge crowds have been demanding he be executed.
In January, former party leader Abul Kalam Azad was found guilty in absentia of eight charges of crimes against humanity and sentenced to death.
In the wake of the public outcry calling for the execution of Abdul Kader Mullah, Bangladesh's parliament earlier this month amended a law which will allow the state to appeal against his life sentence.
The special court was set up in 2010 by the current Bangladeshi government to deal with those accused of collaborating with Pakistani forces who attempted to stop East Pakistan (as Bangladesh was then) from becoming an independent country.
But human rights groups have said the tribunal falls short of international standards. Jamaat and the BNP accuse the current government of pursuing a political vendetta.
