At least 17 of them were shot in clashes between police and protesters that erupted after Delwar Hossain Sayedee, the Jamaat-e-Islami party’s vice president, was found guilty of war crimes, including murder, arson and rape.

He is the third person to be convicted by the much-criticised domestic tribunal whose previous verdicts have also been met with outrage from party who say the process is more about score settling than delivering justice.

The latest clashes brought the overall death toll to 37 since the first verdict was delivered on January 21.

Also among the dead were two policemen who were beaten to death after thousands of Jamaat supporters attacked a base in the northern district of Gaibandha, local police chief Monjur Rahman told AFP.

“At least 10,000 Jamaat supporters attacked us with weapons. We were forced to open fire,” Rahman said, adding two protesters were shot dead.

Seventeen other people were also killed as violence spread all over the country, police said.

About 300 people including scores of policemen were also injured, doctors and police and local media said.

There was no immediate reaction from Jamaat to the verdict, but the party has enforced a nationwide strike demanding a halt to the trials. The cases against eight more Jamaat leaders are still being heard.

Earlier this month the tribunal, a local court with no international oversight, sentenced Jamaat’s assistant secretary general Abdul Quader Molla to life imprisonment.

While angering Jamaat supporters, that verdict also enraged secular protesters, tens of thousands of whom have since poured onto the Shahbag intersection in central Dhaka to demand the execution of Jamaat leaders.

In January the tribunal handed down its first verdict when it sentenced fugitive Muslim TV preacher Maolana Abul Kalam Azad to death.

The tribunal has been tainted by controversies and allegations it is targeting only the opposition with trumped-up charges. Rights groups say its legal procedures fall short of international standards.

The government rejects the accusations, saying the trials are needed to heal the wounds of the war that it says killed three million people.

It accuses Jamaat leaders of being part of pro-Pakistani militias blamed for much of the 1971 carnage.

The government says three million were killed but independent estimates put the figure much lower, between 300,000 and 500,000.
