Summary The blast was caused by an Improvised Explosive Device (IED).
At least nine including four children have been killed while several others injured in a blast near a procession in Thoya Fazil area of Dera Ismail Khan on Saturday.
The roadside device was planted on the route of the procession, police officer Ghulam Ahmed told AFP.
The blast took place as Shiite Muslims were gathering for a procession marking the death anniversary of the Prophet Mohammed s grandson Imam Hussain in 680, and security was tight across the country to prevent attacks.
"The bomb was planted in a dustbin, the blast was powerful and heard several kilometres away," another police official, Siddiq Khan, said.
He said more than a dozen people were wounded in the blast, including a police official.
Pakistan on Friday suspended mobile phone services in major cities to prevent terror attacks against Shiite Muslim commemorations, officials said. Mobile phones are often used to trigger bomb blasts.
Mobile phone services were temporarily blocked in the commercial capital Karachi, the southwestern city of Quetta and several cities and towns in northwestern Khyber Pakhtunkhwa and central Punjab province as well as in parts of the capital Islamabad.
