Parts of central Dhaka turned into a battlefield as protesters attacked police with bricks and sticks in front of the national mosque.

The security forces responded with hundreds of rounds of rubber bullets and tear gas shells, according to witnesses.
The country's 12 Islamic parties called the protests after the weekly prayers in nearly half a million mosques nationwide, demanding the execution of bloggers they say were behind blasphemous writings against Islam and Prophet Mohammed.

One person was killed during the clashes in western district of Jhenidah, district police chief Altaf Hossain told AFP, adding that hundreds of protesters also clashed with ruling party activists.

"The person, most probably a supporter of an Islamic party, died on the way to hospital," he said.

Fierce clashes also occurred in the port city of Chittagong, the northern city of Bogra and dozens of other cities and towns where police fired rubber bullets at thousands of protesters, leaving scores injured, police and local media said.
