The blast took place near the convoy of National Peoples Party’s candidate Dr Ibrahim Jatoi in Shikarpur who remained unhurt.
In another incident, three people were reported injured when a bomb exploded in Balochistan’s Dera Murad Jamali region.
The blast took place near the convoy of an independent candidate for PB-32, Allah Dino, in the district’s Kachchi Pul area.
Rescue teams had reached the site of the attack and started an operation.
Earlier on Tuesday, Pakistan Peoples Party, Muttahida Qaumi Movement and Awami National Party alleged that they were being compelled to boycott the May 11 elections.
Senator Shahi Syed of ANP, Rehman Malik of PPP and Dr Farooq Sattar of MQM addressed a joint press conference at MQM’s ‘Nine Zero’ headquarters over the attacks targeting candidates and workers of the three parties.
During the press talk, Dr Sattar said world powers wanted to bring a government of rightwing parties in Pakistan just to ensure their safe exit from Afghanistan.

Long queues of vehicles were witnessed on the National Highway during the road’s blockade. Later, however, protesters agreed to clear the highway following negotiations with the administration.
