The funeral is being held for Pakistani opposition leader Benazir Bhutto.
Bhutto was assassinated Thursday, after an election rally in Rawalpindi, Pakistan.
It sparked violent protests across the country.
Benazir Bhutto's body returned to her ancestral home in Sindh province Friday morning for burial.
There was international shock and condemnation of the gun and suicide bomb attack that killed Benazir Bhutto in Rawalpindi on Thursday following a huge rally of her hugely popular and pro democratic party.
Political analysts are saying inside Pakistan that this assassination is the worst set back for democracy in that troubled and nuclear armed country.
Pakistan's interim prime minister said earlier Friday that at least for now January 8th parliamentary elections would go ahead as planned.
Meanwhile, thousands of her supporters vented their anger and grief in the streets and across the country.
Reports of dozens of banks, shops and cars torched.
But much of Pakistan ground to a halt Friday as Pakistanis begin their three days or mourning called by President Pervez Musharraf.
Musharraf earlier blamed the attack on terrorists and FBI sources are saying, according to radical Islamist websites, Al Qaeda has claimed responsibility.
But the validity of those claims has yet to be established.
Her funeral began around 3 a.m. Friday morning.
She has been placed in her family's mausoleum, in southern Pakistan, beside her father's grave.
Hundreds of thousands of mourners showed up to pay their respects.
