The bombs that targeted the world renowned pilgrimage town of Bodh Gaya and Mahabodhi Temple complex had a mix of ammonium nitrate and sulphur and were neatly packed in small cylinders, a preliminary report has said.
A team of the National Security Guard (NSG), which picked up samples from the area, has sent a report to the Union Home Ministry, saying the low-intensity bombs worked like improvised explosive devices (IEDs) and were trigerred through analog clock timers.
The NSG post-blast analysis also said that some splinters were put in the ammonium nitrate, sulphur and pottasium emulsion for causing damage in various locations in the temple complex. The explosives were packed and kept in small cylinders which are used for commercial purposes.
The NSG team, which reached the spot on Sunday evening, will return only after collecting more samples from the area, a senior official said on Monday.
