Pakistan attacks kill 28 as leaders meet for summit

A suicide bomber struck a night-time Shiite march in Pakistan, in the bloodiest attack of a day of violence that left at least 28 people dead. 

Police in the garrison city of Rawalpindi said the attack was on the procession of minority Shiite Muslims en route to a mosque. 

In addition to the 28 people killed, a rescue service spokesman said 32 people were wounded including nine children.

Rawalpindi is adjacent to the capital Islamabad, where thousands of extra police and paramilitary forces have been mobilised for a summit of Islamic leaders aimed at promoting trade and investment.
