On Thursday a suicide bomber killed 10 people at a mosque in Balochistan province. A radical Sunni group had threatened violence during the holiday.
No group, however, has said it carried out Friday's bombing. A crowd of Shia men and women dressed in black was marching in the streets of Jacobabad when it was hit by the explosion.

The violence came despite extra security measures in the run-up to Ashura on Saturday, when Shia Muslims hold massive rallies to mourn the death of Imam Hussein, a grandson of Prophet Muhammad.
The Sunni Muslim militant group Lashkar-e-Jhangvi had claimed Thursday's bombing in the Bolan district Balochistan and threatened more attacks against Shia.
