A terrorist group took responsibility for it though. But look at the items used. Anything familiar?
The only thing familiar is the shrapnel elements.
In Hyderabad, Ammonium Nitrate was the primary explosive ingredient used, which produces a more powerfull blast radius collateral wise.
In Boston, the primary explosive was Black Powder, viz., Gunpowder (sulfur, charcoal, and potassium nitrate) comprising the ingredients for these two IED's.
Both were homemade in pressure cookers off site, then transported to the site's location before the starting of the marathon that was the target.
Ammonium Nitrate and Black Powder (gunpowder) are two differing yields of explosives. So yes, in this case, there are similarities such as the element of shrapnel, which even here contained ball bearings, BB shot, and nails were used as the element for shrapnel, which were in fact similar but not exact in Hyderabad.
Notwithstanding as well, the Hyderabad bombing used a more sophisticated means of igniting the IED there versus the simpler battery & timer ignition method (the individual -singular- concocted a most rudimentary ignition device) used by the perpetrator in Boston.
Fork sakes, I just read my reply. I sound like I'm on a board of inquiry making a statement to the Joint Chiefs Of Staff for crikey's sake!:lol::nono:
Update @"Coder-san": Updated my comment above to reflect a line more in agreement with yours whilst carefully wording the two main differences both horrendous bombings.
