Pakistan march: Confusion over Imran Khan 'gunshots'

Clashes have erupted in Pakistan after an attack on a convoy of protesters heading to the capital Islamabad, led by opposition politician Imran Khan.

A crowd pelted the convoy with stones in the city of Gujranwala. Officials from Mr Khan's party said his vehicle was also shot at, but that he was not hurt.

The BBC's Shumaila Jaffery said that people at the procession had denied hearing gunshots.
