Former Prime Minister Imran Khan suffered a bullet injury after a gunman opened fire where he was leading a rally in Wazirabad on Thursday.

According to Azhar Mashwani, an official with Khan’s Pakistan Tehreek-e-Insaf party, Khan was shot in the leg.

Mashwani, however, disclosed that there were six others, including another politician, Faisal Javed Khan, also reportedly injured in the attack.

Khan, who had been leading a protest march to the capital, Islamabad, demanding snap elections, was taken to a hospital in Lahore.

As per the report, the identity of the gunman, who was arrested by police at the scene, was not revealed and no group has claimed responsibility for the attack.

Prime Minister Shehbaz Sharif issued a statement condemning the incident and asked authorities to immediately institute an investigation.

Khan began his long march on October 28 from Lahore and expected to reach Islamabad on November 11.

His government was removed in April this year through a parliamentary vote of no confidence. Since then, Khan has been launching demonstrations across the country, demanding early elections.
