Introduction 
On 13 December 2001, the Indian Parliament in New Delhi was targeted in a coordinated terrorist attack by armed militants aiming to strike at the heart of India’s democratic system. The assault shook the nation, led to significant legal proceedings, and became a watershed moment in India’s counter-terrorism history.

Timeline of the Attack — Minute by Minute
Morning of 13 December 2001
📌 11:28–11:40 AM:
Parliament was in session during the winter session. Due to heated debate, both houses were adjourned about 40 minutes before the attack began, but many MPs, officials and staff remained inside the building.
📌 11:40–11:45 AM:
A white Ambassador car bearing fake Ministry of Home Affairs / Parliament labels entered the Parliament complex through a security gate.
📌 11:45 AM:
Five heavily armed terrorists exited the vehicle near a security point close to where the Vice-President’s car was parked and opened fire on security personnel using AK-47 rifles, grenade launchers, pistols and grenades.
📌 11:45 AM – 12:15 PM:
A gunfight lasting over 30 minutes erupted between the terrorists and security forces (Parliament Security Service, Delhi Police, CRPF and others). All five attackers were killed before they could enter the main Parliament building.

Casualties & Victims
The attack resulted in the deaths of several security personnel and civilians:
Confirmed fatalities (outside the attackers):
  • Five Delhi Police personnel
  • One Central Reserve Police Force (CRPF) trooper
  • Two Parliament Watch & Ward staff
  • One gardener
  • One photojournalist (died later of injuries)
  • Total confirmed deaths (excluding the 5 attackers): ~10.

Injuries
About 15–18 persons were injured in the firing and blast fragments.
Modus Operandi (Operational Tactics)
1. Deception & Infiltration
The attackers used a vehicle with forged official labels to breach outer security layers. This identification deception allowed them to reach a critical point close to Parliament quickly.
2. Armament & Assault
The terrorists were equipped with:
  • Automatic rifles (AK-47s)
  • Pistols
  • Grenades & grenade launchers
Their intention, inferred from the level of armament and prior reconnaissance, was to inflict maximum damage and reach deeper into the Parliament complex.
3. Shock Tactics
A close-range firefight and grenade use maximised shock and confusion, forcing security personnel into immediate containment and defensive action.

Investigation & Forensic Findings
After the incident, investigative agencies (Delhi Police Special Cell, forensic teams and intelligence units) collected substantial evidence:
1. Vehicle & Material Forensics
The forged car passes and labels were analysed to trace their origin and suspected handlers.
Weapons and ammunition were matched with shell cases at the scene.
2. Ballistic & Explosion Analysis
Ballistic examinations confirmed the use of high-velocity weapons.
Explosive residues from grenades and detonators were examined by forensic labs. 
3. Digital & Physical Evidence
A laptop found with suspect Afzal Guru was examined; court records noted it contained data linking it to the attackers and planning phase the day before the attack.
4. Witnesses & Interrogations
Statements from captured associates and witnesses helped identify network links between the attackers and handlers elsewhere.

Accused & Legal Proceedings
  • Main Suspects & Arrests
  • Mohammad Afzal Guru (primary accused, alleged conspirator)
  • Shaukat Hussain Guru (cousin of Afzal)
  • Afsan (Afshan) Guru (Shaukat’s wife)
  • S.A.R. Geelani (lecturer, initially accused)
These individuals were arrested by the Delhi Police in the weeks following the attack.

Charges & Trial
The trial was conducted under multiple statutes:
  • Indian Penal Code (IPC): sections including 121 (waging war against the state) and 120B (criminal conspiracy).
  • Prevention of Terrorism Act (POTA), 2002 (terrorism framework).
  • Explosive Substances Act (for bomb-related offences).
  • The Special Court examined over 80 prosecution witnesses and extensive documentary evidence.

Court Verdicts
  • Afzal Guru: Convicted and sentenced to death; Supreme Court upheld the sentence in 2005. He was executed on 9 February 2013.
  • Shaukat Hussain Guru: Sentenced (initially death, later commuted to imprisonment).
  • Afsan (Afshan) Guru: Convicted for limited offence (concealment); acquitted of major involvement.
  • S.A.R. Geelani: Initially convicted but acquitted on appeal due to insufficient evidence.

Suspect Networks & Attribution
Indian investigative agencies attributed the attack to Pakistan-based terror organisations — primarily Jaish-e-Mohammed (JeM), with involvement and training links suggested to Lashkar-e-Taiba (LeT). Pakistan’s Inter-Services Intelligence (ISI) was repeatedly accused by Indian officials of providing guidance, an allegation Pakistan officially denied.

Strategic and Security Impact
1. National Security Changes
CISF (Central Industrial Security Force) deployment strengthened around Parliament.
Security protocols radically revised for high-value political institutions.
2. India–Pakistan Relations
The attack led to a major standoff between India and Pakistan in late 2001–2002, with both nations mobilising troops along the border before international diplomatic intervention eased tensions.

Lessons from Forensic & Legal Process
  • Forensic Takeaway
  • Multi-modal evidence (ballistics, physical objects, digital media) provided a cohesive case.
  • Chain of custody and expert analysis were crucial in connecting suspects to the crime.
  • Legal & Procedural Lessons
  • Use of POTA sparked debate on civil liberties.
  • The admissibility and weight of evidence (like the laptop data) became subjects of legal scrutiny.

Conclusion
The 2001 Parliament attack remains one of India’s most serious internal security incidents — not only for its direct loss of life and threat to a national institution, but for its impact on law enforcement practices, legislative reforms and Indo-Pak relations. The incident serves as a case study in modern terrorism response, forensic methodology, and judicial process.
