An anti-government strike has closed schools and stores and disrupted traffic in Bangladesh's capital.
Opposition groups, led by former prime minister Khaleda Zia, called for the dawn-to-dusk general strike to protest against government moves to amend the constitution.
The government wants to repeal a provision that requires it to hand over power at the end of its term to a nonpartisan caretaker administration to oversee elections.
Police said the strike shut down schools and shops in Dhaka, a city of 12 million people. Most buses and cars were off the roads.
No strike-related violence was reported - a working day in Bangladesh - but police said protesters set fire to at least 11 buses on Saturday.
