Islamabad- Four days ahead of Aug 14 ‘Azadi March’ by Pakistan Tehreek-e-Insaf in Islamabad, authorities on Sunday sealed the Red Zone in the federal capital. Security forces have been deployed for security in Islamabad, with holidays of education institutions extended till Aug 17 in the wake of PTI’s massive anti-government protest march. All roads adjacent to the Red Zone have been sealed with containers. Defiant Imran Khan, the PTI chief, has refused to budge from his stance. Despite political efforts aimed at refraining him from the plan, Khan has vowed to hold the show at all cost, demanding Prime Minister’s resignation and seeking inquiry into vote rigging.
