(RFE/RL) — A suicide bomber has killed at least 13 people at Shi’ite processions in the city where the Pakistani army is headquartered.
The blast ripped a hole in the walls of a Shi’ite mosque in the city of Rawalpindi, near the capital Islamabad.
There was no immediate claim of responsibility for the bombing.
Sunni militants in Pakistan have stepped up attacks on the country’s Shia community in recent months.
The attack occurred hours after two bomb blasts killed at least three people near a gathering of Shi’ites in Pakistan’s commercial hub and biggest city Karachi.
The violence came on the eve of today’s summit of eight developing nations in Pakistan.
Pakistan, Iran, Egypt, Turkey, Indonesia, Malaysia, Nigeria and Bangladesh are expected to discuss ways of boosting trade and investment at an event which Islamabad hopes will improve its standing.
