QUETTA -- The "Islamic State of Iraq and Syria" (ISIS) claimed the suicide bombing at a political rally in Mastung Friday (July 13) that killed over 100 people, AFP reported.
The blast in Balochistan Province was the deadliest in a string of attacks on political rallies in recent days ahead of nationwide polls on July 25.
According to senior provincial official Saeed Jamali, the bomber detonated in the middle of a compound where a political meeting was taking place.
The explosion killed Siraj Raisani, who was running for a provincial seat with the newly formed Balochistan Awami Party (BAP).
The explosion comes hours after four people were killed and 39 injured when a bomb hidden inside a motorcycle detonated near a Pakistani politician's convoy in Bannu on Friday, near the Afghan border.
The earlier bomb targeted the convoy of Muttahida Majlis-e-Amal (MMA) candidate Akram Khan Durrani, who survived the attack, police said.
On Tuesday (July 10), a bomb claimed by the Pakistani Taliban targeted a rally by the Awami National Party (ANP) in Peshawar.
Local ANP leader Haroon Bashir Bilour was among the 22 killed. Thousands flocked to his funeral the next day.
