Summary The blast occurred in a closed bakery shop.
A bomb attack on a Shiite Muslim procession killed seven people and wounded more than 135 in northwest Pakistan on Sunday as Shiites marked their holiest day Ashura, police said.
The bomb exploded in the city of Dera Ismail Khan in Khyber Pakhtunkhwa province, where a blast on Saturday killed nine people near a Shiite Muslim procession.
Nazir Khan, a police official in the city, said the bomb was planted inside a shop. "It was a remote-controlled bomb and exploded as a procession reached here," he said.
Khalid Aziz, a doctor in the city s main hospital said the condition of some of the injured was critical.
Pakistan has deployed tens of thousands of police and paramilitary forces to try to avert attacks on Ashura processions, when Shiites whip themselves to mourn the seventh-century killing of the Prophet Mohammed s grandson Imam Hussain.
Authorities have ordered heightened security, with services for mobile phones -- which are often used to trigger bombs -- suspended in major cities.
The Pakistani Taliban claimed responsibility for Saturday s attack.
It also claimed a suicide attack that killed 23 people last Thursday at a Shiite procession in the garrison city of Rawalpindi.
