In Pakistan, a suicide bomber dressed in military uniform has attacked the UN World Food Programme offices in the capital Islamabad, killing five people. Four of the dead are Pakistanis, the fifth is an Iraqi. The bomber also died. Local television TV footage showed smoke rising from the heavily fortified UN building and shattered windows, shortly after the early afternoon blast in the building’s reception area.Interior Minister Rehman Malik said the bomber was dressed in a Frontier Corps uniform and asked to go inside to use the toilet. Earlier, a WFP employee told local television the explosion took place within the compound, close to the main building, where there were about 100 people working at the time. The WFP said three of its staff members had been confirmed dead and several others had been injured, with two in a critical condition. Reports say sniffer dogs have been brought in and investigators are on the roof. The building is now ringed by heavily armed anti-terror police. It is unclear who is responsible but suspicion will fall on the Pakistani Taliban.
