Former Pakistani lawmaker Imran Khan, who hopes to become the next prime minister, has condemned a bombing near the election rally of a rival candidate, where four of the candidate's supporters were killed.
Khan in a tweet says there seems to be a conspiracy to sabotage the July 25 vote. But he says the people of Pakistan will not allow anything to prevent "historic" elections from taking place.
Four people were killed and 20 others wounded in the bombing near the rally of Akram Khan Durrani, who is running for a seat in parliament from the northwestern city of Bannu. Durrani was about to leave the rally at the time.
Khan is facing tough competition from Durrani, who is the candidate of an alliance of religious groups.

Officials say disgraced ex-Prime Minister Nawaz Sharif will be whisked away by helicopter to the federal capital of Islamabad when he returns to Pakistan's eastern city of Lahore from London to face a 10-year jail sentence on corruption charges.
Sharif is to return at 6 p.m. Friday from London where he has been visiting his ailing wife. He is to be accompanied by his daughter Mariam, who was sentenced to seven years in prison.
Sharif's son-in-law is currently serving his one-year prison sentence.
Sharif is expected to appeal his conviction and seek bail.
Ahead of his return, police swept through Lahore, arresting scores of Sharif's Pakistan Muslim League party workers to prevent them from greeting him at the airport.
