Pakistan ? The triple bombing of a religious procession in Pakistan adds to the strains on a government already struggling with devastating floods and shows that Islamist militants are back in business despite the natural disaster.

The death toll in the blasts rose to 35 on Thursday, with about 250 injured, government official Sajjad Bhutta said.

The bombs late Wednesday ripped through a Shiite Muslim street procession in the sprawling city of Lahore, which has been frequently targeted by Sunni extremists over the last two years, often in coordinated attacks on religious minorities.

Sunni extremists have launched dozens of attacks against Shiites and other Islamic sects and religions in Pakistan in recent years. The extremists believe it is permissible — even honorable — to kill members of other faiths.
