The decline of insurgency, the fate of the militant groups behind Assam’s deadliest attacks, and what the numbers tell us about violence today.
In October 2008, Guwahati was struck by one of the deadliest terrorist attacks in Assam’s history. Bombs exploded at Ganeshguri, Panbazar and other locations across the state as part of a coordinated series of attacks that killed scores of people and injured hundreds. The blasts came amid a wider insurgency involving groups seeking secession, autonomy and separate homelands, alongside ethnic conflict and militant violence.
Nearly two decades later, Assam’s security landscape looks substantially different. Major peace agreements have been signed, thousands of militants have surrendered, and insurgency-related fatalities have fallen dramatically from their earlier levels. The strongest evidence of change comes from the long-term decline in insurgency-related deaths across Assam, rather than from a single measure of crime in Guwahati.
2008: When insurgency shaped Assam’s security landscape
The scale of the problem is visible in the South Asian Terrorism Portal’s historical data (SATP). In 2008, Assam recorded 1,500 insurgency-related fatalities and arrests, according to data compiled from the Union Ministry of Home Affairs (MHA) and published by the SATP. The breakdown was:
Civilians killed: 245
Security force personnel killed: 18
Militants (killed/arrested/surrendered combined) : 1,237
Total insurgency-related fatalities/arrests : 1,500
The violence was not confined to Guwahati either. Lower Assam experienced militant attacks and ethnic conflict, while the North Cachar Hills region faced abductions, extortion and killings linked to the Dima Halam Daogah (Jewel Garlosa) faction. The principal militant organisations identified by the Ministry of Home Affairs included the United Liberation Front of Asom (ULFA), the National Democratic Front of Bodoland (NDFB) and the DHD(J) faction.
The state was also experiencing acute ethnic violence. Communal clashes in Udalguri and Darrang between October 3 and 5, 2008, killed 57 people and injured 117, according to the Ministry of Home Affairs’ 2008–09 annual report. The violence displaced residents, many of whom were accommodated in temporary relief camps.
The October 30 blasts: Who was responsible?
Nine bombs exploded at locations across Assam, including Ganeshguri and Panbazar in Guwahati, as well as sites in Kokrajhar, Barpeta Road and Bongaigaon. The attacks struck crowded public places, including markets and transport areas.
The precise casualty totals differ between contemporary reports and later judicial records. The Ministry of Home Affairs’ annual report recorded 76 deaths and 351 injuries from the October 30 attacks. Later court reporting and judicial records put the death toll at approximately 87–88, with hundreds injured.
Investigators attributed the attacks to the Ranjan Daimary-led faction of the National Democratic Front of Bodoland (NDFB), an insurgent organisation seeking a separate Bodoland. A special court convicted 15 NDFB cadres in January 2019. The proceedings involved hundreds of witnesses and extensive documentary evidence.
In 2019, the court sentenced NDFB founder Ranjan Daimary and nine others to life imprisonment, according to The Indian Express. Other convicted defendants received different sentences, including some who had already served their terms. Daimary had been arrested in Bangladesh in 2010 and handed over to India.
The attacks were not an isolated event. On January 1, 2009, three more blasts struck Guwahati, killing five people and injuring more than 50, according to contemporary reporting. A further blast at Maligaon on January 9 killed three and injured 20. On March 31, another explosion at Jyotikuchi killed one person and injured 16. Four blasts across Assam on April 6 killed seven and injured 63.

The sequence illustrates how, in the months surrounding the 2008 attacks, bombings were a recurring security threat rather than an exceptional event. To reiterate, the 2008 blasts were not an isolated incident. Assam was facing multiple insurgent movements, ethnic violence, kidnappings, extortion and attacks on civilians and security personnel. Organisations such as ULFA, NDFB, DHD and other tribal armed groups terrorised ordinary citizens.
Insurgency related fatalities from 2002-2010The numbers: From 387 insurgency incidents to single-digit annual fatalities
The clearest evidence of Assam’s transformation is the reduction in insurgency-related violence recorded by the Ministry of Home Affairs.
The following figures come from the ministry’s North-East Insurgency Profile, reproduced in its historical data tables. The numbers count insurgency-related incidents and casualties across Assam as a whole, not Guwahati city alone.

The trend is striking. Recorded incidents fell from 387 in 2008 to eight in 2023, a decline of approximately 97.9%. The annual figure did not fall uninterruptedly: it rose in 2009, again in 2012–2014, and slightly in 2021. Nevertheless, the long-term decline is unmistakable.
Civilian deaths also fell from 245 in 2008 to nine in 2015 and seven in 2018.
What happened to the Militant Organisations?
The decline is partly explained by the weakening, surrender or political accommodation of several insurgent organisations.
1. National Democratic Front of Bodoland (NDFB)
The NDFB was responsible for the 2008 serial blasts according to the investigation and subsequent convictions. But the organisation later fragmented, with different factions taking different positions on negotiations.
A major turning point came with the Bodo Peace Accord, signed on January 27, 2020. The agreement led to the surrender of 1,615 NDFB cadres, according to SATP’s account of the accord.
The agreement was intended to resolve the long-running Bodo conflict through political arrangements, rehabilitation and development measures. The result was a significant reduction in the NDFB’s organised armed presence. The organisation’s former factions are no longer comparable to the insurgent force that carried out the 2008 attacks.

2. United Liberation Front of Asom (ULFA)
ULFA’s trajectory illustrates both the progress and the limits of Assam’s peace process.
The organisation split over negotiations with the government. The pro-talks faction, led by Arabinda Rajkhowa, signed a tripartite peace agreement with the Centre and Assam government on December 29, 2023. In January 2024, the faction formally disbanded under the terms of the agreement.
The agreement followed decades of conflict. It committed the pro-talks faction to abandon violence and enter the political mainstream, while providing for measures addressing development, indigenous rights and political demands.

Assam has not eliminated insurgency; it has brought a large part of the older insurgent movement into negotiations while leaving a smaller, still-active armed faction outside the settlement.
3. Other militant groups
The same process affected other organisations. In 2021, the Karbi Anglong agreement brought more than 1,000 armed cadres into the mainstream, according to SATP’s assessment. In April 2023, the Dimasa National Liberation Army (DNLA) signed a peace agreement and 168 cadres laid down their arms. In July 2023, 1,182 cadres belonging to eight Adivasi militant organisations surrendered.

These figures are evidence of demobilisation on a substantial scale. They also show why the decline in insurgency-related violence cannot be attributed to policing alone: negotiations, rehabilitation and political settlements were part of the change.
Why Did Terrorism Decline?
The evidence points to several developments working together. First, the insurgency itself became less lethal. The decline in recorded incidents from 387 in 2008 to eight in 2023 reflects a dramatic contraction in organised insurgent violence.
Second, peace agreements brought significant sections of militant organisations into the political mainstream. The 2020 Bodo Accord, the 2021 Karbi Anglong agreement, the 2023 DNLA settlement and the December 2023 ULFA agreement all contributed to demobilisation and reduced armed activity.

Third, arrests, surrenders and the dismantling of militant networks reduced the operational capacity of several organisations. The 2020 Bodo Accord alone resulted in the surrender of 1,615 NDFB cadres, while 1,182 cadres from eight Adivasi organisations surrendered in 2023.
Finally, city-level policing data indicate improvements in crime detection and case disposal in recent years. The Guwahati Police Commissionerate reported that its chargesheeting rate rose from 19.13% in 2023 to 68.34% in 2025, while its conviction rate rose from 4% in 2021 to 28.5% in 2025. These are indicators of criminal-justice performance, rather than direct measures of violence.

It is difficult to isolate the precise contribution of each factor. The figures establish a strong association between peace agreements, demobilisation and declining insurgency-related violence.
- Sustained Security Operations: Intelligence gathering arrests, counter-insurgency operations and the dismantling of militant networks weakened armed organisations.
- Peace Negotiations: The government pursued negotiations with groups willing to abandon violence and work within the constitution.
- Surrender and Rehabilitation: Former militants were encouraged to lay down arms and return to civilian life.
- Economic development and employment improved infrastructure, industrial development and employment opportunities helped expand economic alternatives, particularly for the state’s youth.
- Political Accommodation: Long standing demands relating to identity, autonomy, representation and development were addressed through negotiated settlements and autonomous councils.
Peace was pursued through both security measures and political engagement.
A City and State Transformed
Guwahati and Assam have moved a considerable distance from the security environment of 2008. The October 30 serial bombings, repeated attacks in 2009, ethnic clashes and the wider insurgency belonged to a period when organised political violence was a much more prominent feature of life in the state.
The numbers illustrate the scale of the change. Assam’s recorded insurgency incidents fell from 387 in 2008 to eight in 2023. Recent police figures show that total registered crime in Guwahati declined by 38.4% between 2023 and 2025. Meanwhile, peace agreements have brought thousands of former militants into the mainstream.
The Assam of 2026 is vastly different from the Assam of 2008. The serial bomb blasts, recurring insurgent attacks and widespread armed mobilisation that once defined the state’s security challenges have declined dramatically. The numbers tell the story.
October 30th is not merely an anniversary of a terrorist attack. It is a reminder of the lives lost, the families devastated and the years of insecurity Assam endured. But it is also an opportunity to measure how far the state has travelled. The victims of October 30 must never be forgotten. And the peace Assam has achieved must never be taken for granted.
