So far, the terrorists have been using ammonium nitrate-based bombs in serial blasts across the country. Police authorities now say that the Student Islamic Movement of India (SIMI) had been experimenting with a new combination of hydrogen peroxide(H2 O2) to make liquid bombs.
Some preliminary liquid bombs were first experimented with in the Vagamon forests in Idukki district of Kerala where a SIMI camp was held in December 2007. The experiments with hydrogen peroxide had been revealed by SIMI general secretary Safdar Nagori during interrogation.
Police officials opine that liquid bombs can be as potent as the ones which use ammonium nitrate. The concoction can be injected in plastic or glass bottles of soft-drinks and detonated without attracting much attention.
Officials said the soft-drink bottles could be placed in crates or stacked in closed goods carriers and then detonated. SIMI planned to use food colours to make these bombs look like the original beverage. They had also figured out how to fix the batteries and detonators for triggering the device.
Nagori stated that this bomb-making technique was first introduced to the SIMI cadres by Hyderabad-based Raziuddin Nasir who had been trained at the Dera Ismail Khan terror training camp in Pakistan.
