Murtaza Bhutto, the elder of the two sons of Zulfiqar Ali Bhutto, was a left-wing revolutionary. He took to arms after his father was put to gallows by the military dictator Muhammad Zia-ul-Haq in dubious circumstances. He shifted his base to Afghanistan, where a post-Soviet invasion communist government was more than willing to provide him with sanctuary and training.
Soon after, Pakistani young men in groups started to cross over the hazardous mountains in packs to join his international organization "al-zulfiqar"-a militant wing of the Pakistan People's Party, a left wing organization. KHAD offered help, and Bhutto willingly accepted while exploring other options in Tripoli (Lebanon), Damascus (Syria) and war-torn Beirut (Lebanon). Beirut seemingly, was his love, as Karachi was the love of his father. Later, he married Lebanese-Syrian Ghinwa Bhutto, who now runs the Pakistan People's Party Shaheed Bhutto (PPP-SB).
Bhutto's group made numerous attacks on military and state infrastructure. Salamullah Tipu, the terror of Karachi, was his lieutenant, who was later put before a firing squad on what critics argue, Murtaza's behest.
Bhutto campaigned as an independent in the 1993 elections, winning a seat in the assembly governing the Sindh province. In 1995 he led a schism of the ruling Pakistan People's Party.
In 1996, he accused police of unfairly targeting his organization and denied playing any part in bombings in Karachi that year. On 20 September 1996, he was shot and killed along with six supporters during an altercation with the police. The police stated that Murtaza and his supporters had refused to allow police to search their vehicles as part of security measures imposed since the bombings, and that they were fired upon first. The assassination took place in the posh locality of Clifton, Karachi. According to area residents the gunfire continued unabated for hours.
Benazir Bhutto was the prime minister of Pakistan at the time of Murtaza Bhutto's killing. The brother and sister were estranged at the time and were political opponents. To date the assasination of Murtaza Bhutto remains an unsolved case.
