Benazir Bhutto's father:
Benazir Bhutto's father, former Prime Minister Zulfikar Ali Bhutto, was removed from office following a military coup in 1977 led by the then military chief General Muhammad Zia-ul-Haq, who imposed martial law but promised to hold elections within three months. But later, instead of fulfilling the promise of holding general elections, General Zia charged Mr. Bhutto with conspiring to murder the father of dissident politician Ahmed Raza Kasuri. Mr. Zulfikar Ali Bhutto was sentenced to death by the martial law court.
Despite the accusation being "widely doubted by the public", and despite many clemency appeals from foreign leaders, Zulfikar Ali Bhutto was hanged on 4 April 1979. Appeals for clemency were dismissed by acting President General Zia. Benazir Bhutto and her mother were held in a "police camp" until the end of May, after the execution.
Begum Nusrat Bhutto:

Both brothers Murtaza Bhutto and Shahnawaz Bhutto married two Pashto sisters from the royal Afghani family. After the alleged involvement of Shahnawaz's wife Rehana in the murder of Shahnawaz, Murtaza Bhutto divorced his wife.
On July 18, 1985, the 27 year old Shahnawaz was found dead in Nice, France. He died under mysterious circumstances, and the Bhutto family firmly believed he was poisoned. No one was brought to trial for murder, but Shahnawaz's wife Rehana was considered a suspect by the French authorities and remained in their custody for some time. She was found not guilty and later allowed to travel, and went to the United States. Pakistani media, which was under Zia's control, attributed his death to drug and alcohol abuse.
Shahnawaz is believed to have helped organize a group dedicated to overthrowing the regime of President Mohammed Zia ul-Haq, through links to Al-Zulfiqar, increasingly active in Pakistan at that time.
The funeral of Shahnawaz turned into a defiant show of opposition to Zia's military rule. It was held in a Larkana sports stadium, attended by an estimated 25,000 people.
