KEY POINTS:
GARHI KHUDA BAKHSH - Benazir Bhutto was laid to rest next to her father in the family mausoleum after the opposition leader's assassination plunged Pakistan into crisis and triggered violent protests.
Tens of thousands of mourners wept and beat their heads as Bhutto, killed by a suicide attacker at an election rally on Thursday, was carried from her ancestral home in Sindh province, in the south of the country, to the domed mausoleum.
The 54-year-old's death stoked fears a January 8 election meant to return Pakistan to civilian rule could be put off amid a backlash threatening to engulf embattled President Pervez Musharraf.
Pakistan said there were signs al Qaeda was responsible.
"We have intelligence intercepts indicating that al Qaeda leader Baitullah Mehsud is behind her assassination," an Interior Ministry spokesman said. Mehsud is one of Pakistan's most wanted militant leaders.
Bhutto's husband, Asif Ali Zardari, wept as he accompanied her coffin, draped with the green, red and black tricolour of Bhutto's Pakistan People's Party, on the 7km journey to the tomb in the dusty village of Garhi Khuda Bakhsh.
He then prayed there with the couple's three children, son Bilawal, 19, and daughters Bakhtawar, 17 and Aseefa, 14.
Many mourners chanted slogans against Musharraf and the United States, which has long backed the former army general in the hope he can maintain stability in the nuclear-armed country racked by Islamist violent.
"Shame on the killer Musharraf, shame on the killer US," mourners cried.
Others wept in despair. "Bhutto was my sister and Bhutto was like my mother," cried farmer Imam Baksh. "With her death, the world has ended for us."
Musharraf, who seized power in a military coup in 1999 but left the army last month to become a civilian president, has appealed for calm and blamed Islamist militants for the killing.
But many accused him of failing to protect Bhutto, who died in the garrison city of Rawalpindi, home of the Pakistani army.
In Sindh, where Bhutto had huge popular support, particularly among the rural poor, officials said 24 people, including four policemen, were killed in protests.
"We're anticipating the situation might get worse after the funeral," Sindh Interior Minister Akhtar Zaman said.
World leaders urged Pakistan to stay the course towards democracy, as Bhutto's death rattled markets and triggered a flight to less risky assets such as bonds and gold.
"Unrest in Pakistan is eroding the market sentiment dramatically as Pakistan, unlike North Korea or Iran, is known to really have nuclear weapons," said Koichi Ogawa, chief portfolio manager at Daiwa SB Investments.
In Sindh, authorities issued an order to shoot violent protesters on sight. Hundreds of cars, trucks and buses smouldered in the interior of the province and crowds of men set up road blocks and chanted slogans against Musharraf.
Meanwhile, a blast at an election meeting in Pakistan's troubled northwest killed six people including a candidate for the party that supports Musharraf, police said.
There were also sporadic protests elsewhere in the country and one person was killed in the eastern city of Lahore.
Bhutto returned home from self-imposed exile in October, hoping to become prime minister for a third time.
But as she left the rally she stood to wave to supporters from the sun-roof of her bullet-proof car. An attacker shot at her before blowing himself up, police and witnesses said.
She was killed by bullets to the head and neck.
"The shooter was either very well trained or he was very close so he could hit her in the temple and neck," a security official said.
She was buried alongside her father, former Prime Minister Zulfikar Ali Bhutto, who was hanged in 1979 after being deposed by a military coup. Her two brothers, Murtaza and Shahnawaz, who both died in unexplained circumstances, are also buried in the mausoleum she herself had ordered to be built.
The United States, which relies on Pakistan as an ally against al Qaeda and the Taleban in neighbouring Afghanistan, had championed the Harvard- and Oxford-educated Bhutto.
Her death dashed US hopes of a power-sharing agreement between her and Musharraf.
President George W Bush condemned "this cowardly act by murderous extremists" and urged Pakistanis to honour Bhutto's memory by going ahead with the election.
"Elections stand as they were announced," Prime Minister Mohammadmian Soomro told reporters. But analysts said the assassination, which followed a wave of suicide attacks and the worsening of an Islamist insurgency, could make this impossible.
"If it's left to Pervez Musharraf then he will try to ram it through but on the ground it's going to be very difficult," said Talat Masood, a retired general and political analyst.
"Now voices are being raised that he is the problem and not the solution as the Americans think," he said. "He may be a casualty as a result of that."
Those comments were echoed by Rasul Bakhsh Rais, professor of politics at the Lahore University of Management Sciences.
"Opposition forces are going to converge on a single point. That's the removal of Pervez Musharraf from the political scene and the power structure," he said.
Former Prime Minister Nawaz Sharif, who was deposed by Musharraf in the 1999 coup, said his party would boycott the January election and blamed Musharraf for the instability.
Musharraf imposed a state of emergency in November in what was seen as an attempt to stop the judiciary from vetoing his re-election as president. He lifted emergency rule this month.
In 1988, aged just 35, Bhutto became the Muslim world's first democratically elected woman prime minister. Deposed in 1990, she was re-elected in 1993, and ousted again in 1996 amid charges of corruption she said were politically motivated.
Bhutto escaped unhurt from a suicide attack in October that killed at least 139 people.
She had spoken of al Qaeda plots to kill her. But she also had enemies in other quarters including among the powerful intelligence services and some allies of Musharraf.
