16 people have died in clashes in Bangladesh during a strike over a death sentence given to an Islamist party leader.

The Bangladeshi government deployed troops to the town of Bogra, where eight people were killed in clashes between police and Islamist party supporters.

Bangladesh has been rocked by protests and counter-protests since January, when a tribunal set up by the government to investigate abuses during the war of independence against Pakistan handed down its first conviction, sentencing a leader of the Jamaat-e-Islami party in absentia to death.

About 60 people have been killed in protests since the tribunal's third conviction on Thursday, when another member of the Islamist party, Delwar Hossain Sayedee, 73, was sentenced to death for abuses including murder and rape during the war.

He denied the charges and his lawyer said he would appeal. Another party member was sentenced to life in prison on Feb. 5.

Thousands of Jamaat-e-Islami activists took to the streets of Bogra town, 220km north of the capital, Dhaka, today and attacked police with crude bombs, swords and sticks, police and witnesses said.

They stormed a police station and set fire to houses including those of leaders of the ruling Awami League party, reporters said.

"We had to open fire after rubber bullets and teargas failed to disperse the attackers," police officer Atiur Rahman said.

An army spokesman in Dhaka said two platoons of troops had been deployed in the town.

Eight people were killed in Bogra and eight were killed in clashes elsewhere, according to reports from police.

Bogra is a political stronghold of Begum Khaleda Zia, head of the main opposition Bangladesh Nationalist Party (BNP) and arch rival of Prime Minister Sheikh Hasina.

The two women have shaped the country's politics since 1991, both serving terms as prime minister followed by spells in opposition. They routinely accuse each other of political vengeance and provoking violence.

Today is the first day of a three-day strike called by the Jamaat-e-Islami and the BNP.

Ms Hasina set up the tribunal in 2010 to investigate abuses during the war that claimed about three million lives. Thousands of women were raped.

The two opposition parties say the prime minister is using the tribunal to persecute them.
