A female reporter has been brutally slapped on live television by a Pakistani national guard, inciting a mixed response from social media critics.

Saima Kanwal was in the middle of a live broadcast in Karachi, Pakistan, when both she and her cameraman were confronted by a Frontier Constabulary (FC) trooper and told to stop filming, India Today reports.

Emphasising her right to report the news, Kanwal diverted her camera to the trooper, in a bid to shame him.

As Kanwal tried to confront the FC, the male trooper shoved her hand away then slapped her across the face.

“Gulbahar police have registered a case against the FC personnel over charges of conducting aerial firing and assaulting modesty of the female reporter of K-21 TV channel by slapping her," police told Pakistani media.

Remarkably the video has garnered a mixed response from critics, with some supporting he FC’s violent actions.

“If women are being respected in Pakistan that deosnt (sic) mean that they can cross their limits! well done guard (sic),” one user wrote.
