Details were sketchy in the immediate aftermath. Police at first said a pair of back-to-back roadside bombs exploded.

Finally police concluded that the carnage was the work of a pair of suicide bombers

All officials spoke on condition of anonymity because they were not authorized to release the information.

The Islamic State group later claimed responsibility for the attacks in a statement posted by its Aamaq news agency, confirming that the blasts came from a pair of suicide bombers.
