A bomb exploded near a Shi'ite religious procession in northwest Pakistan killing seven people, including four children, officials say.
At least 30 people, including five children, were also hurt when the bomb exploded on the route of a minority Shi'ite community procession in the Dera Ismail Khan district, local hospital chief Aziz Baluch said.
The blast happened as Shi'ite Muslims gathered for a procession marking the anniversary of the death of the Prophet Mohammed's grandson and security was tight across the country to prevent attacks.
The bomb was in a dustbin and the blast was heard several kilometres away, said police.
Pakistan on Friday suspended mobile phone services in major cities to prevent terror attacks against Shi'ite Muslim commemorations, officials said.
Mobile phones are often used to trigger bomb blasts from a distance.
