Operation Sindoor
"India's May 2025 military strikes on nine terror camps in Pakistan and PoK in response to the Pahalgam attack"
Operation Sindoor was a precision military operation conducted by India from May 7–10, 2025, in which Indian armed forces struck nine terrorist infrastructure sites in Pakistan and Pakistan-occupied Kashmir (PoK). The operation was India's direct response to the Pahalgam terror attack of April 22, 2025, in which 26 Hindu civilians (primarily tourists) were killed by terrorists linked to Lashkar-e-Taiba. Operation Sindoor resulted in approximately 100 terrorists killed, and was followed by a ceasefire understanding on May 10, 2025.
Highest UPSC relevance for GS2 (India-Pakistan relations, national security, cross-border terrorism), GS3 (Internal Security), and Interview. Operation Sindoor is the most significant India-Pakistan military engagement since the 1999 Kargil War and has redefined India's counter-terrorism doctrine — establishing that India will hold Pakistan accountable for terror attacks originating from its territory.
- 1 Pahalgam attack (April 22, 2025) — 26 Hindu civilians killed in J&K's Baisaran Valley; LeT-linked perpetrators
- 2 Operation Sindoor dates — May 7–10, 2025; precision strikes using BrahMos, loitering munitions, and air assets
- 3 Targets — 9 terror camps across Pakistan (Punjab, KPK) and PoK; approximately 100 terrorists killed
- 4 India suspended Indus Waters Treaty in response to the Pahalgam attack
- 5 Pakistan closed airspace to Indian flights; suspended trade; recalled diplomatic staff
- 6 Ceasefire understanding — May 10, 2025; described as a 88-hour conflict
- 7 India's post-Sindoor posture — Army messaging in April 2026 stated 'Operation Sindoor continues' — signalling ongoing operational readiness
- 8 India-Pakistan bilateral freeze — no formal talks, closed border, suspended water treaty as of April 2026
- 9 India's SCO participation (April 2026) tests multilateral diplomacy alongside bilateral freeze
Rajnath Singh's attendance at the SCO Defence Ministers' meeting in Bishkek (April 28, 2026) — less than a year after Operation Sindoor — raises the central question of whether India can sit at the same multilateral table as Pakistan's defence minister while maintaining its counter-terrorism position.
