Mumbai: Ammonium Nitrate was used as explosive substance to carry out the triple blasts in Mumbai on Wednesday evening. Union Home Secretary RK Singh said that Improvised Explosive Devices which used ammonium nitrate and electronic detonators were used in the blasts. Singh said that the IEDs showed that they were not crude devices but indicated sophistication.
Revealing that the blast at the Opera House was of the strongest intensity out of the three, Singh said that 11 people were killed and 73 injured when the IED placed below a garbage can exploded.
The blast at Zaveri Bazaar left six people dead and 50 others injured while the IED at Kabootar Khana in Dadar was a low-intensity one in which 10 were injured. The IEDs at Zaveri Bazaar and Dadar were hidden near a motorcycle under an umbrella and on a bus shelter respectively, said Singh
1 kg of ammonium nitrate was used in Opera House, 400-600 grams at Zaveri Bazaar and 200 grams in Dadar.
Singh added that the investigations into the terror strike were being carried out jointly by the Mumbai Police Crime branch, National Security Guards, National Investigation Agency and Central Forensic Science Laboratory.
Almost 1 kg of ammonium nitrate was used to carry out the blast in Opera House, 400-600 grams were used at Zaveri Bazaar and 200 grams in Dadar.
The methodology and the substance used to carry out the dastardly terror strikes point to the involvement of Indian Mujahideen the group is known to use ammonium nitrate.
Talking about the investigation into the three blasts at Dadar, Zaveri Bazaar and Opera House in Mumbai, Union Home Minister P Chidambaram also said the forensic evidence have already been collected from blast sites and that ammonium nitrate was used with timer mechanism in the blasts.
Sources have also told CNN-IBN that since vehicles were ostensibly used to plant bombs at two of the three spots, two alleged Indian Mujahideen operatives Mohammed Mobin Abdul Shakoor Khan alias Irfan (32) and his cousin Ayub Raja Amin Shaikh (28) arrested by the Maharashtra Anti-Terrorism Squad on July 6 will be questioned as these operatives had allegedly supplied the cars which were used to plant bombs in the Gujarat serial blasts of 2008.
A seven-member team of Central Forensic Science Laboratory (CFSL) from New Delhi and another five-member team from Pune are investigating the blast sites. A team of National Security Guards team has also joined the investigations.
