KARACHI, Oct 21: Investigators have concluded that Thursday’s blasts in Benazir Bhutto’s homecoming procession were caused by twin sui-

cide bombings of varying intensities, sources close to a top police investigation team told Dawn.

The Sindh police chief had on Thursday night told the me-

dia that the first blast was caused by a hand-grenade and the second was of a suicide bombing.

However, during the course of investigation police have reached an opinion that the first blast was also result of a suicide bombing, although it was of less intensity compared with the second blast.

On Friday morning, during the evidence gathering from the blasts site, police found a severed head, with its one side intact. Police with the help doctors planned to carry out a reconstruction surgery of the face so that it could become identifiable, a senior police officer told Dawn on condition of anonymity.

Since the provincial police chief had stated that the first blast was caused by the hand-grenade, no police officer was wiling to contradict his statement by coming on record, he added.
