Uttar Pradesh had its worst brush with terror on Friday when blasts ripped through three cities in the state.
While this attack remains UP's worst incident, the fact remains that the state has increasingly becoming a hot bed for terrorist outfits since 2001.
Intelligence Bureau reports point out that there are 23 terror cells operating in Uttar Pradesh.
The first time a major terror operation was busted in Uttar Pradesh was in 2001 when the police foiled a major bid to attack the disputed makeshift temple at the Ram Janmabhoomi site and killed three terrorists.
The Intelligence Bureau says there are 130 terror modules including sleeper cells that operate across the country, most of which are in Uttar Pradesh.
Reports suggest terrorists favour UP for two reasons. Varanasi and Ayodhya are hot on the terror list because any attack in these places could cause communal violence across the country.
The blasts in Hyderabad were aimed at causing communal tension.
Even the Ajmer Dargah blasts were aimed at causing communal tension, the IB says.
The UP blasts that took place in court premises were aimed at both creating communal tension and also to send across a strong message to the judiciary which is hearing the Ram Janmabhoomi case.
