On Thursday, Bhutto had told of the risks she faced."I put my life in danger and came here because I feel this country is in danger. People are worried. We will bring the country out of this crisis," Bhutto told the Rawalpindi rally. India, Pakistan's giant neighbour and rival, said Bhutto's assassination was a terrible blow to the democratic process.
Bhutto became the first democratically elected female prime minister in the Muslim world in 1988 at the age of 35. She was deposed in 1990, re-elected in 1993, and ousted again in 1996 amid charges of corruption and mismanagement.
She said the charges were politically motivated.
Bhutto's husband, Asif Ali Zardari, arrived in Islamabad from Dubai to collect his wife's body and take it for burial in Larkana, the Bhutto ancestral home where her father is buried. Both of her brothers died in mysterious circumstances.
