In certain cities with more sensitive situation, the government has already enforced a partial cellular service suspension on Muharram 8.
Amid rampant militancy and sectarianism, stringent security arrangements have been put in place to avoid any untoward incident on Ashura days.
Authorities imposed restrictions in parts of Srinagar on Friday to prevent a traditional Muharram procession, officials said.
In order to keep law and order situation under complete control, the government also made a decision to ban pillion riding in sensitive cities of the country, including Karachi, Quetta and Peshawar, as part of Ashura security arrangements.
In Karachi, the key procession began from Nishter Park and culminated at Irania Hussainia Imambargah.
In Quetta and Peshawar, the processions were taken out from Rehmantullah Chowk on Alamdar Road and Imambargah Agha Syed Ali Shah Rizvi, respectively.
Cellular and internet services remained suspended in Karachi, Jacobabad, Shikarpur, Kashmore, Khairpur, Haripur, DI Khan and Lakki Marwat, among other areas.
The police received intelligence inputs about miscreants trying to incite trouble during the procession scheduled for later in the day.
With regard to further security and safety inside of the procession, followers and mourners will be required to enter via walk-through gates, installed with metal detectors.
