Operation Sindoor

Overview

Operation Sindoor was a series of Indian missile and air strikes launched in the early hours of 7 May 2025 against nine sites in Pakistan's Punjab province and Pakistan-administered Kashmir. India stated the operation was carried out in direct retaliation for the 22 April 2025 Pahalgam attack, in which militants killed 26 civilians, most of them Hindu tourists, in the Baisaran Valley meadow near Pahalgam.

The strikes targeted infrastructure that India attributed to Lashkar-e-Taiba (LeT), Jaish-e-Mohammed (JeM), and Hizbul Mujahideen, including camps at Muridke, Bahawalpur, Sialkot, Muzaffarabad, Kotli, and Bhimber. The Indian government named the operation "Sindoor" — a reference to the vermilion powder worn by married Hindu women — a symbolic gesture toward the widows of the men killed at Pahalgam, several of whom were reportedly targeted and killed in front of their wives.

The operation marked the most significant Indian military action against targets inside Pakistan since the 2019 Balakot airstrike, and triggered four days of cross-border strikes, artillery exchanges, and aerial engagement before a ceasefire was announced on 10 May 2025.

Key Provisions

India characterised Operation Sindoor as a "focused, measured and non-escalatory" response directed exclusively at terrorist infrastructure, stating that no Pakistani military installations were targeted and that site selection was intended to avoid civilian and military collateral damage. The Indian Ministry of Defence framed the action as an exercise of its right to respond to cross-border terrorism attributable to Pakistan-based groups, consistent with the doctrine India had applied following the 2016 Uri attack and the 2019 Pulwama attack.

The operation was conducted by the Indian Air Force using a mix of air-launched stand-off missiles and loitering munitions, without Indian aircraft or personnel crossing into Pakistani airspace, according to Indian officials. Nine sites were struck within a reported window of approximately 23 minutes.

Pakistan disputed India's characterisation, stating that the strikes hit civilian areas including a mosque compound at Ahmedpur Sharqia near Bahawalpur, and reported that at least 31 civilians were killed, including children. India's Defence Minister Rajnath Singh stated on 8 May that the strikes had killed more than 100 militants.

Implementation

Following the initial strikes on 7 May, Pakistan responded with artillery fire along the Line of Control and claimed to have shot down multiple Indian aircraft, a claim India did not confirm in full. Over the following three days, both countries exchanged drone incursions, artillery fire, and claims of strikes on airbases and military infrastructure, with each side disputing the other's damage claims.

On 10 May 2025, following mediation efforts led by the United States, India and Pakistan announced a ceasefire, halting what analysts described as the most intense direct military exchange between the two countries since 1971. Both governments claimed to have achieved their military objectives, and each accused the other of violating the ceasefire's initial hours before the halt in hostilities held.

In the aftermath, India also announced the suspension of the Indus Waters Treaty, expelled Pakistani diplomatic personnel, and closed the Wagah-Attari border crossing, measures that remained in effect after the ceasefire.

Effectiveness and Criticism

Indian officials and government-aligned commentary presented Operation Sindoor as a successful demonstration of long-range precision strike capability and a recalibration of India's response threshold to cross-border terrorism, arguing it degraded militant infrastructure and imposed a cost on Pakistan-based groups without provoking full-scale war.

Independent and international assessments have been more mixed. Analysts at institutions including the Stimson Center and Carnegie Endowment noted that verified damage to militant infrastructure was difficult to confirm independently, that both sides' casualty and damage claims were contested, and that the episode exposed the risks of rapid escalation between two nuclear-armed states operating with limited crisis-communication channels. Pakistani officials and rights groups disputed India's targeting claims, pointing to reported civilian deaths, including at the Bahawalpur mosque compound, as evidence that the strikes were not as precise as India claimed.

The crisis renewed debate over the durability of India-Pakistan de-escalation mechanisms and the precedent set by the suspension of the Indus Waters Treaty, a water-sharing agreement that had survived previous wars between the two countries. Commentators noted that the underlying drivers of the conflict, cross-border militancy emanating from Pakistan-based groups and the unresolved status of Kashmir, remained unaddressed by the four-day exchange.
