There have been at least five deadly attacks against similar shrines in Pakistan over the past two years.
While the attacks are motivated by religious differences, they also appear aimed at provoking sectarian warfare and making the government look weak because it is failing to protect the people.
The practice of visiting shrines is common among Muslims across South Asia, and those who do so insist they are not doing anything that contravenes Islamic law. The attacks on shrines have caused anger, but many people — including educated, middle-class Pakistanis, choose to believe in conspiracy theories that hold Americans or other non-Muslim foreign powers responsible.
Also Monday, the bullet-riddled body of a Pakistani tribal elder was found, six weeks after he was abducted, intelligence officials and a local resident said. The two intelligence officials spoke on condition of anonymity because they were not authorized to talk to the media.
Sardar Amanuddin had urged displaced members of the Mehsud tribe to return to South Waziristan, a tribal area where the army has battled the Pakistani Taliban. The Taliban previously warned the tribesmen against coming back. Mr. Amanuddin’s body was found near Wana, the main town in the tribal region.
Jan Aalam, a shopkeeper at a local paramilitary base, confirmed that Mr. Amanuddin’s relatives had brought his body to the base, seeking a vehicle to transport it outside South Waziristan.
