The Islamabad police have said that section 144 is in force in the city and the security is on “high alert”, as the PTI is set to begin its countrywide protests.

Without directly referring to any scheduled protests, it said that there could be increased traffic near the F9 park and urged the public to avoid “unnecessary travel” on the nearby routes.

The police said that special forces of the Counter Terrorism Department had been deployed on patrol to deal with any emergency.

“Patrolling has been increased across the district while checking has been tightened at checkpoints,” it added.
