Riot police in Bangladesh have fired rubber bullets and sprayed tear gas at hundreds of demonstrators who attacked government offices in the capital Dhaka.
The demonstrators were protesting against two days of almost constant power outages.
Reports indicated about 200 protesters were injured in the clashes.
The violence broke out in Dhaka’s northern Mirpur district, where nearly a 1000 stone-throwing demonstrators rampaged through the streets.
Some Dhaka residents have been getting just two hours of electricity a day.
Public anger has been heightened because the power cuts have affected devotees trying to offer special evening prayers for the Islamic holy month of Ramadan.
