Pakistan Tehreek-e-Insaf (PTI) leader Omar Ayub on Tuesday reiterated the demand for holding snap polls in the country.

Expressing his thoughts, Ayub said: "September 9 was the blackest day in the country's history. The parliament was attacked during the last night and early morning."

"I have complained from Ayaz Sadiq that how did he give the permission for entry," Ayub lamented.
