Popular support for Musharraf declined when Nawaz Sharif successfully made a second attempt to return from exile, this time accompanied by his younger brother and his daughter. Hundreds of their supporters were detained before the pair arrived at Iqbal Terminal on 25November 2007. Nawaz Sharif filed his nomination papers for two seats in the forthcoming elections whilst Benazir Bhutto filed for three seats including one of the reserved seats for women. Departing an election rally in Rawalpindi on 27December 2007, Benazir Bhutto was assassinated by a gunman who shot her in the neck and set off a bomb. The exact sequence of the events and cause of death became points of political debate and controversy. Early reports indicated that Bhutto was hit by shrapnel or gunshots, but the Pakistani Interior ministry maintained that her death was due from a skull fracture sustained when the explosive waves threw her against the sunroof of her vehicle. The issue remains controversial and further investigations were conducted by the UK police. The Election Commission announced that due to the assassination the elections, which had been scheduled for 8January 2008, would take place on 18February.
