Suspected ultra-left extremists overnight shot dead three policemen at a remote area in Bangladesh's northwest Pabna district, officials said on Wednesday.
"The extremists suddenly fired gunshots killing instantly our camp in-charge and two other policemen at remote Daspara area in Pabna district," Pabna's Assistant Police Superintendent Jamil Ahmed told reporter over phone.
Ahmed said police sub-inspector Kafiluddin and the two others came under the sudden attack of the suspected operatives of a faction of the banned Maoist outfit Burba Banglar Communist Party (Lal Pataka) as they went to a nearby village bazaar last night to collect fuels for cooking.
"They all were unarmed as the extremists gunned them down," Ahmed said, adding that an initial report said a police informant too was killed but it later turned out to be false.
Police said the motive behind the killing was not clear but the incident came as security experts in recent months feared Maoist uprising in northwestern and western regions as a massive campaign was underway to uproot extreme rightwing Islamist militants.
Several ultra left groups operate in the region.
