Pakistani investigators are trying to identify a charred body believed to be that of the suicide bomber who blew himself up in a crowded mosque Friday, killing 31 people.
The investigators say no one has come to claim the body. The provincial government has offered a reward of 10 million rupees, about $170,000, for information leading to the identity of the suicide bomber.
The attack in the city of Sialkot sparked rioting Saturday by Shi'ite Muslims. Tensions remained high Sunday, but no incidents were reported.
No one has claimed responsibility for the bombing. But Pakistani officials say it may have been a reaction to the killing of the country's most wanted terrorist suspect, Amjad Hussain Farooq, in a gun battle with police a week ago.
