Soldiers were patrolling Bangladeshi cities on Saturday to quell growing civil unrest sparked by student demonstrations, with riot police firing on protesters who defied a government curfew. This week’s violence has killed at least 123 people so far, according to an AFP count of victims reported by police and hospitals, and poses a monumental challenge to Prime Minister Sheikh Hasina’s autocratic government after 15 years in office. A government curfew went into effect at midnight and the premier’s office asked the military to deploy troops after police again failed to subdue widespread mayhem. “The army has been deployed nationwide to control the law and order situation,” armed forces spokesman Shahdat Hossain told AFP. The curfew will remain in effect until at least 10:00 am (0400 GMT) Sunday, private broadcaster Channel 24 reported. Streets in the capital Dhaka were almost deserted at daybreak, with troops on foot and in armoured personnel carriers patrolling the sprawling megacity of 20 million. But thousands returned to the streets later in the day in the residential neighbourhood of Rampura, with police firing at the crowd and wounding at least one person. “Our backs are to the wall,” protester Nazrul Islam, 52, told AFP at the scene. “There’s anarchy going on in the country… They are shooting at people like birds.” Hospitals have reported a growing number of gunshot deaths to AFP since Thursday. “Hundreds of thousands of people” had battled police across the capital on Friday, police spokesman Faruk Hossain told AFP. “At least 150 police officers were admitted to hospital. Another 150 were given first aid treatment,” he said, adding that two officers had been beaten to death. “The protesters torched many police booths… Many government offices were torched and vandalised.” Staff at the Dhaka Medical College Hospital told AFP that another two police officers were killed on Saturday, while four people admitted to intensive care succumbed to their injuries. Two more protesters were killed in the industrial town of Savar on Dhaka’s outskirts, a major centre of Bangladesh’s garment exports. Enam Medical College Hospital spokesman Zahidur Rahman confirmed the latter deaths to AFP, adding that “nine people came here with bullet wounds”. A spokesman for Students Against Discrimination, the main group organising the protests, told AFP that two of its leaders had been arrested since Friday. Hasina had been due to leave the country on Sunday for a planned diplomatic tour but abandoned her plans after a week of escalating violence.
