The May 1988 Pathankot Blasts: When Insurgency Spilled into Himachal Transits
Between May 9 and May 18, 1988, security forces launched Operation Black Thunder II to clear militants from the Golden Temple in Amritsar. In the immediate days that followed, militant groups launched massive, coordinated retaliatory strikes across Punjab and neighboring borders, averaging roughly 20 fatalities per day.
The Casualties & Pathankot Sector
- 45 Total Fatalities: Recorded across Punjab and neighboring Himachal Pradesh borders within a tight 24-hour window.
- 14 Killed / 100+ Injured: Resulted from a rapid succession of 7 coordinated bomb blasts in and around the Pathankot town transit lines on Friday, May 20.
- Indefinite Curfew: Imposed immediately across Pathankot town that Friday evening to contain the situation and prevent further blasts.
The Targeting of HRTC Buses Historically, this specific window marked a distinct and tragic shift in tactics—expanding the geographic reach of the violence by intentionally targeting civilian commuters traveling into the hills.
>“This is the first time that terrorists have blown up HRTC (Himachal Road Transport Corporation) buses. Early this month, groups of terrorists made three attempts to intercept HRTC buses and fire upon them between Chandigarh and Ambala national highway.” — The Indian Express, May 21, 1988
The Kandwal Barrier Detonation
- The Target: HRTC Bus (Route: Leaving Pathankot toward Kangra district).
- The Location: The explosives detonated just after the bus crossed the Chakki Bridge, right as it approached the Kandwal entry barrier (the Himachal border checkpoint).
- The Toll: 4 passengers were killed and 20 others were severely injured in this single blast.
