PPP leader Aseefa Bhutto-Zardari was injured after a drone camera struck her at the party's anti-government march in Punjab's Khanewal on Friday, video footage aired on television showed.
The video showed Aseefa, who was standing atop a container alongside her brother and PPP chief Bilawal Bhutto-Zardari, lurching backwards as she attempted in vain to get out of the drone's way.
The drone, which was mounted with a camera, was being used for the media coverage of the march, media reported, adding that Aseefa went inside the container after the device hit her.
Following the incident, Bilawal's security staff got hold of the drone operator, according to media, which quoted Bilawal as saying that it was not clear whether the incident was an accident or the consequence of a deliberate act.
Punjab government spokesperson Hassan Khawar said the government responded immediately after the incident.
"The Rescue 1122 team and duty doctor Dr. Babar (General surgeon at DHQ hospital) who were stationed next to container, immediately went into the container. Ms. Aseefa Zardari suffered a minor cut on eyebrow and bruises on her hand," he tweeted.
