Imran Khan's convoy fired upon during rally

Imran Khan, the former Pakistani prime minister, has reportedly been injured in a shooting attack targeting his supporters as they marched on the capital Islamabad.

Unidentified gunmen opened fire on the vehicle carrying Mr Khan as it passed through Wazirabad, Pakistan’s Dawn newspaper reported on Thursday.

At least four PTI leaders, including chairman Imran Khan, were injured after unidentified armed men opened fire.

Video footage from the scene shows Mr Khan and his supporters riding on top of a shipping container towed by a lorry before a burst of gunfire is heard. Mr Khan is then seen ducking, as those around him try to cover him.

Another video shows a conscious Mr Khan with a bandage on his right leg being taken away in a vehicle after the shooting.
