Lucknow: Three forensic teams trying to get to the root of the Varanasi terror attack that killed two people still don't know what explosives were used.
The deafening blast at Shitla Ghat on the Ganga banks during the routine evening 'arti' Dec 7 claimed two lives and left about 30 injured.
Besides the first team of forensic experts airlifted from Agra on the same night to study the nature of the blast, another team was summoned from Gujarat. A third team went to Varanasi from Lucknow Sunday.
What appears to have left everyone clueless was the absence of any detonator.
"It was really mind boggling that there was no trace of any detonator in the vicinity of the blast," said a police official.
"That was what led us wonder if the explosive used was something unfamiliar," he said. "And that has become some kind of a challenge for us."
Meanwhile, the Anti-Terrorist Squad (ATS) of Uttar Pradesh Police is understood to be zeroing in on an Indian Mujahideen module alleged to have carried out the blast on the bank of the Ganga.
"While there is some reason to believe the blast was masterminded by IM bigwigs in Sharjah, some threads were being traced to Azamgarh," said an officer.
"However, we have yet to get any concrete evidence to establish that," the source said.
But the officer was confident of getting to the root of the blast "very soon".
