The bombs planted in Surat did not go off as their integrated circuit chips had faulty programme, sources in the forensic laboratory, where the unexploded bombs were examined, said on Friday.
The Directorate of Forensic Science, after detailed analysis of unexploded bombs, said it has been found out that the programming of the integrated circuit chips in the bombs were faulty due to which they did not explode, sources in DFS in Gandhinagar said today.
As many as 25 bombs were found from various localities of Surat after the Ahmedabad blasts -- in a plan by terrorists to target the diamond hub of the country -- but none of them went off.
All the other components of Surat bombs were up to the mark, like the batteries used as detonators and the explosive in the form of Ammonium Nitrate gel, the sources said.

"Surat bombs were different from those used in Ahmedabad as those which exploded in Ahmedabad had timers while those in Surat had the integrated circuit chips," the sources added.
The analysis was trying to find out when the bombs were programmed and what kind of technology was used behind their programming, they said.
