The PTI Secretary General Asad Umar told to media that an unknown gunman opened fire at an open container in the Wazirabad area where Khan was standing along with other political leaders to lead a rally.
Umar added that Khan got a bullet injury at his leg and had been shifted to a local hospital for treatment, adding that his condition was out of danger, according to Dawn.
Prime minister Shehbaz Sharif has taken notice of and “severely condemned” the firing incident at Imran Khan’s long march container in Wazirabad.
He has instructed Interior Minister Rana Sanaullah to seek an immediate report on the incident from the IGP and chief secretary Punjab, according to a tweet from the Government of Pakistan’s official Twitter account.
Other injured included a senator and two regional political leaders, Umar added.
Police have reportedly arrested two suspects after the shooting.
No group or individual has claimed the attack yet.
Police personnel have cordoned off the area and launched a search operation.
