2007 Karsaz bombing
The Karsaz bombing attack occurred on 18 October 2007 in Karachi, Pakistan; it was an attack on a motorcade carrying former Prime Minister Benazir Bhutto. The bombing occurred two months before she was assassinated. The bombing resulted in at least 180 deaths and 500 injuries. Most of the dead were members of the Pakistan Peoples Party (PPP). The bombing 

The streets of Karachi ground to a halt to welcome the return of Benazir Bhutto, after an eight-year self-imposed exile during which she lived in Dubai and London. Two explosions occurred in front of the rallying truck from which she greeted her supporters and party members at approximately 00:52 PST, on the route about halfway from the airport to the tomb of Muhammad Ali Jinnah for a scheduled rally, just after Bhutto's truck had crossed a bridge. Police vehicles bore the brunt of the blasts, which completely destroyed three police vans and killed at least 20 policemen in the vehicles. Conflicting reports indicate that Bhutto, who was not injured in the attack, was either sitting on top of the truck or had just climbed into the compartment of the truck at the time of the explosion. Bhutto was escorted to her residence, Bilawal House. The victims were rushed to Jinnah Hospital, Liaquat National Hospital, Civil Hospital and Abbasi Shaheed Hospital. In a press conference on 19 October 2007, Bhutto said that her security team were unable to prevent the attack because of the streetlights being turned off, and called for an inquiry into why this happened. On 20 October, authorities released a photograph of the suspect responsible for the suicide attack. On 23 October, Pakistani Prime Minister Shaukat Aziz rejected Pakistan Peoples Party's demand for a probe into the suicide blast by foreign experts, expressing confidence that Pakistani law-enforcement agencies could probe in a very objective manner. In the immediate aftermath of the attempt on her life, Bhutto wrote a letter to General Pervez Musharraf naming four persons whom she suspected of engineering the attacks. Careful not to name Musharraf himself, she chose to name senior military officials and politicians in Musharraf's regime instead, including Chaudhry Pervaiz Elahi, a rival PML-Q politician and the then chief minister of the province of Punjab, Hamid Gul, former director of the Inter-Services Intelligence agency, and Ijaz Shah, director general of the Intelligence Bureau, another premier military intelligence agency on Pakistan. Musharraf's regime blamed terrorist organisations such as Al-Qaeda and elements of the Taliban in Pakistan instead. Al-Qaeda's chief of operations for Pakistan, Fahid Mohammed Ally Msalam, was believed to be behind the attack. He was killed in a drone strike in Pakistan along with his lieutenant, Sheikh Ahmed Salim Swedan, on 1 January 2009. Tehrik-i-Taliban Pakistan leader Baitullah Mehsud was also implicated in the attack. He was killed in a drone strike in Pakistan in August 2009. Reaction
