The analytical report on recent bombing incidents in the country, compiled with data from all states for the period between April and June this year, also raised concern over the possible leakage and use of ordnance factory-made explosives by terror outfits.

"Analysis of the data by the NBDC shows public was the prime target of the terrorists/militants/insurgents. Public support to terrorists/insurgents continues in some parts of the nation. "Until and unless the public support to anti-national elements stops, the acts of terrorism will continue.

Sincere efforts are required to mitigate the IED menace. A 'Whole of Nation' effort is the way ahead to keep the citizens of the country safe," the report, accessed by PTI, said.

While the report did not elaborate as to how public support was rendered to ultras, it is understood that police forces and other agencies who report these incidents to the National Bomb Data Centre (NBDC) also share inputs with regard to links detected between the locals and perpetrators of such blasts.

The NBDC of the National Security Guard (NSG) is based at its garrison in Manesar near here and acts as the national repository for collection and analyses of all types of bombing incidents and attacks in the country.

Analyses of the incidents of IED recovery/blasts for the second quarter of this year, it added, reveal "in most of the incidents, explosive ordnance like grenades and other forms of explosives which are made in ordnance factories were used by terrorists, militants and insurgents of Jammu and Kashmir and North East."

"In some incidents, Chinese made grenades were also used by militants of Jammu and Kashmir," the report said. It said a total of 93 blast incidents were reported in the second quarter of this year as compared to 92 last year, while 39 people were killed as compared to 60 people last year and 185 injured in comparison to 206 last year.

"There was 1 per cent increase in number of blast incidents during the second quarter of 2016 vis-a-vis second quarter of 2015. There was 16 per cent decrease in the number of casualties which took place in blast incidents in the second quarter of 2016 vis-a-vis same period last year," it said.
