Gunmen on motorcycles stopped a commuter bus carrying Ismaili Muslims in Karachi May 13, boarded it and opened fire on the passengers, killing at least 45. Outside the hospital where some dozen wounded survivors were taken, and where the bus was parked, scores of grim-faced young Ismali men formed a human chain to block everyone but families and doctors—apparently fearing a follow-up attack. English leaflets left in the bus were headlined "Advent of the Islamic State!" The leaflet used derogatory Arabic words, blaming the Ismali community for "barbaric atrocities...in the Levant, Iraq and Yemen." Pakistani media said the attack was claimed by the Tehrik Taliban Pakistan, the Jundullah [10] network, and militants claiming to represent ISIS. (AFP [11], BBC News [12], May 13)
