Masses mourn Pakistan's Bhutto, one year on

More than 150,000 grieving Pakistanis thronged the tomb of slain former premier Benazir Bhutto on Saturday, mourning their beloved leader one year after her assassination.

A sea of sobbing mourners, some wailing and beating their chests in a wrenching outpouring of emotion, flooded through security checkpoints into the graveyard in rural southern Garhi Khuda Bakhsh for the commemoration.

Bhutto, 54, was assassinated on December 27, 2007 in a gun and suicide attack at a campaign rally in the garrison city of Rawalpindi, just two months after returning to Pakistan from exile to vie for a third term in power.

Her shocking death threw the world's only nuclear-armed Islamic nation into chaos, sparking violence and leading to months of political turmoil that ended in September when her widower, Asif Ali Zardari, claimed the presidency.
