This was the fourth terrorist attack on politicians. The spate of attacks on candidates contesting the upcoming polls began on July 10, when a bomb targeted a rally by ANP in Peshawar, martyring local party leader Haroon Bilour along with 21 others. An attack on a Jamiat Ulema-e-Islam-Fazl (JUI-F) convoy in Bannu on July 13 followed the tragic Peshawar incident. The Bannu incident claimed lives of at least four people, while 10 others were injured in the explosion. According to JUI-F leader Akram Khan Durrani, the blast took place near the tyre of his jeep when he was passing through Haved Bazaar after addressing an election rally. Later the same day, in what was one of the deadliest attacks in the country's history, Balochistan Awami Party candidate Nawab Siraj Raisani along with 131 others was martyred when a suicide bomber blew himself up during an election rally in Mastung's Darengarh area.
