Wazirabad: An unidentified person opened fire on former Prime Minister of Pakistan Imran Khan on Thursday at Wazirabad on the way to his long march procession.

Imran Khan received a leg injury from a bullet and he shifted to hospital for treatment. One of his party supporter was killed in the firing and seven others were injured. The police took the assailant into custody. Since his ouster in a no-confidence vote in Parliament in April, Khan has mobilized mass rallies across the country, where he has whipped up crowds with claims that he was a victim of a conspiracy by his successor, Prime Minister Shahbaz Sharif, and the United States.

Pakistan has a decades-long history of political assassinations, including that of Benazir Bhutto, the first democratically elected female leader of a Muslim country, in 2007. The attack on the Khan convoy happened in the Wazirabad district in the Eastern Punjab province where the former cricket star turned Islamist politician was travelling in a large convoy of trucks and cars heading towards the capital, Islamabad. The convoy is part of his campaign aimed at forcing the government to hold early elections.
