Authorities in northwestern Bangladesh say at least seven people were killed and some 100 injured late Monday when police opened fire on a crowd protesting power shortages.
Earlier, police had said five people died in the incident in Chapainawabganj district, northwest of the capital, Dhaka. The authorities did not explain why the death toll had risen.
Local police say the crowd gathered outside the regional electricity office in Shibganj. They say the protest turned violent when demonstrators attacked police and set fire to several police vehicles.
Officials say the protesters were also demanding the release of three village leaders arrested Sunday for their participation in a demonstration earlier this month against frequent power outages.
