The eight blasts that rocked Bengaluru on July 25 points to high orchestration, but low intensity. The blasts reportedly took place within about 12 minutes at around 1-30 pm, that is after the Friday’s mid-day namaz in the local mosques.
The high orchestration used in timing five to six blasts, with some precision, resembled the serial blasts in Jaipur in May last year and in three towns of Uttar Pradesh in November.
While timers were used to activate the improvised explosive devices, the explosive material used does not appear to have been of a sophisticated kind. Ammonium nitrate, mixed with a booster, was the preferred explosive in previous terrorist incidents, but one does not know whether ammonium nitrate was used in the Bengaluru blasts too.
Some TV reports speak of the possible use of gelatin sticks. If so, these blasts would resemble, from the point of view of the composition of the IEDs, the serial blasts in Coimbatore carried out by Al Ummah, a Muslim extremist organisation of South India, in February 1998 to protest against the alleged police excesses against Muslim youth after the demolition of the Babri Masjid. Investigation into the Coimbatore blasts showed that Muslim youth had fabricated the IEDs with the help of explosive material stolen from the quarries of south India.
From preliminary reports, one could make the following surmise: firstly, the terrorists did not want to cause mass casualties; secondly, Bengaluru has the largest concentration of foreign businessmen and experts, but they did not want to target them; thirdly, they did not want to target the foreign tourists either.
