Terrorists Kill Dozens in Pakistan Bombing (updated)

AFP news quotes Pakistan provincial government official: "Information we have received from hospitals and police suggest that the death toll is 57." "Dawn" in Pakistan reports, "At least 56 people were killed and more than 100 injured when a bomb exploded at Karachi's Nishtar Park Tuesday evening when faithfuls were offering Mughrib (Evening Prayers) after attending a mammoth meeting to celebrate the birthday of the Holy Prophet...There was stampede and angry crowd pelted stones on police, damaged and torched vehicles and there was complete chaos in a vast area around the park which is near the mausoleum of the Quaid-e-Azam." AFP reports, "One or possibly two attackers climbed onto a wooden stage in Karachi's historic Nishtar Park as around 50,000 people offered sunset prayers. They then approached the Sunni clerics and detonated powerful bombs." Witness: "“I saw body parts everywhere. I saw people collecting body parts and putting them in ambulances.” CNN with a possible revenge motive: Explosion on "stage set up by Jumaat Ahle Summat, a predominantly Sunni group, Pakistani media reported...In February, at least 40 people were killed when a suicide bomber attacked a Shiite procession in the town of Hangu in the country's North West Frontier Province." "The News" reports that the Jumaat leader was killed in today's blast: "Chief of Tehreek-e-Awam-e-Ahle Sunnat, Haji Mohammad Hanif Billo has also died in the incident." "Dawn" news reports on deaths of several leading Karachi clerics in today's blast: "Haji Hanif Billo, Mulana Abbas Qadri, Hafiz Muhammad Taqi & Iftikhar Bhatti were among the top notch leaders of Sunni Tahreeq/Jamaat Ahl-e-Sunnat who were martyred in the bomb blast at Nishtar park bomb blast, hospital sources said." A leading Shia cleric in Karachi survived a bomb attack just days ago. No group has claimed responsibility as of 1 pm ET.
