A suicide bomber blew himself up in the lobby of the World Food Program in the Pakistani capital of Islamabad on Monday, killing three people and wounding several others, police and witnesses said, according to AP. The blast in the lobby of the heavily fortified and guarded building left victims lying on the ground in pools of blood and shattered windows, witnesses said. Al-Qaida and Taliban militants have carried out scores of suicide attacks in Pakistan over the last 2 1/2 years, a number of them targeting foreigners and their interests. Police officer Bin Yamin said the attacker was between 22 and 25 years old and detonated his explosives in the lobby. He said three people were killed, including an Iraqi working for the WFP. Several others were injured, two of which were in a critical condition, the WFP said in a statement.
