A suicide bomber has killed up to eight paramilitary police at a tented camp in Pakistans capital, the second such attack in Islamabad in less than two weeks, officials said. It was the latest in a wave of bomb attacks that have killed more than 1,700 people in the nuclear-armed key US ally since government forces fought gunmen holed up in a radical Islamabad mosque in July 2007.[imagebrowser id=10450]
