Pakistan has banned cell phone service until the end of Ashura to prevent anymore terrorist attacks.
A suicide bomber killed 37 Shia protesters this weeek.
Pakistan has suspended mobile phone services in major cities, a move officials say is necessary to prevent terror attacks from marring Shia Muslim processions.
“All the blasts that occurred within the last 15 days were mobile-phone based,” Interior Minister Rehman Malik told reporters on Friday.
Mobile and wireless phone services were temporarily blocked in the commercial capital Karachi, the southwestern city of Quetta and in parts of the capital.
The Pakistan Telecommunications Authority (PTA) said the suspension was likely to continue until Ashura, the climax of the month of Muharram, on Sunday.
“The wireless phone service will most likely be suspended for the next two days just the way it was today,” Akhlaq Hussain, a director of PTA, told AFP.
