Pakistan has imposed Section 144 in Rawalpindi and sealed all roads leading to Adiala Jail ahead of major protests planned by Imran Khan's party, PTI. Heavy security has been deployed as PTI leaders and supporters prepare demonstrations demanding access to the jailed former Prime Minister. Imran Khan's sister is expected to lead the protest. The restrictions come amid heightened political tensions and fears of unrest around the high-security prison where Khan is being held.
