This was Bhutto's first public engagement since the attack in Karachi and the PPP has restricted her movements, saying she faced threats to her life.
From the airport, she drove in an armoured SUV through dusty village roads to Garhi Khuda Bux, 28 km from Islamabad, to pray at the tomb of her father, late prime minister Zulfiqar Ali Bhutto.
Bhutto, wearing a maroon salwar-kameez and her trademark white scarf, emerged through the SUV's sun roof and waved to the crowd. But she appeared tense and nervous when the vehicle was surrounded by scores of people at the airport and at the tomb.
Many PPP supporters gathered alongside the road, waving the party's red, black and green flags and shouting slogans like "Long Live Bhutto" and "Prime Minister Benazir". Many party workers rode motorcycles that trailed her convoy.
