An Islamic seminary student hurled a shoe at former prime minister Nawaz Sharif on Sunday.

Nawaz Sharif, who was ousted last year over graft charges, appeared visibly shocked as the shoe hit his shoulder while he was addressing a gathering at a seminary in Lahore.

The incident came a day after an individual hurled ink at Foreign Minister Khawaja Asif, a member of the ruling party and a close Sharif aide, while he was speaking at a party rally in eastern Pakistan.

The shoe hurling was broadcast live on TV channels.

The perpetrator then jumped on stage where Nawaz was standing and began chanting before he was overpowered by the crowd and handed over to the police.

According to police officials, the man is a student at the seminary.

Minutes later, Imran Khan, leader of the Pakistan Tehreek-e-Insaf opposition party and an arch rival of Sharif who has frequently criticised the former prime minister, condemned the incident.

"This is not the way to express yourself and I condemn whoever did it," Khan said.

Sharif, a three-time prime minister, was ousted by the judiciary in July 2017 over corruption charges which he is currently facing in Pakistani courts.
