"The city of Hyderabad was not as lucky the following year. On 21 February 2013, two powerful explosions shook the city. Ammonium Nitrate was used to make the bombs that took seven lives. The modus operandi of these bombings had an IM signature yet again. It proved that a series of arrests might have weakened its network, but it was certainly not out of the game. Sushil Kumar Shinde, the then Home Minister, confirmed that intelligence agencies had some prior information about the attack. However, there was no input about the place of the attack. The blast reignited the debate on security preparedness. The Manmohan Singh government found it hard to explain how an attack had occured despite intelligence inputs. The theory of saffron terrorism and the support of Afzal Guru by some politicians encouraged Pakistan to deny its hand in the terrorist activities before the UN and other international forums it used both as a ruse to deny its role in sponsoring terrorism in India. India’s soft stance to carry forward the dialogue process was further emboldening the Pakistani state."
