Bangladesh police fired tear gas and used batons to stop thousands of opposition activists trying to march to the prime minister's office on Tuesday (September 12) to demand electoral reforms. Protesters also exploded crude bombs at several places in the city, but there were no reports of any casualties or damage, witnesses said. Several police vehicles were attacked with stones. At least 100 people were injured in the clashes that erupted in Dhaka after opposition members tried to break past barbed-wire barricades around Begum Khaleda Zia's office
