SIALKOT, Pakistan (AP) – Thousands of minority Shiite Muslims rampaged through an eastern Pakistan city Saturday in a riot sparked by a suicide bombing at a Shiite mosque that killed 31 people.

Rioters set fire to a police station and the mayor’s office in Sialkot, destroyed several motorcycles and attacked a court. Firefighters rushed to the scene, while troops tried to restore order.

“The army is handing the situation, but violence is still going on,” said Mohammed Irfan, an official at the city’s police control room.

There were no immediate reports of injuries.

The violence broke out after about 15,000 mourners, beating their chests and wailing, gathered for a funeral for victims of Friday’s bombing at the Zainabia mosque, which also wounded more than 50 people.

The attack came less than a week after Pakistani security forces killed Amjad Hussain Farooqi, a top Pakistani al-Qaida operative who was a member of a radical Sunni Muslim militant group – leading to speculation the bombing was retaliation for his death.

The bombing touched off angry protests by Shiite young people Friday, who ransacked shops and gas stations and damaged dozens of vehicles. Army troops were deployed in the city amid fears of sectarian unrest despite appeals by Shiite clerics for calm.
