Tensions between India and Pakistan have once again flared up, this time in the international waters of the North Arabian Sea. On the evening of September 15, 2026, a Pakistan Navy vessel collided with a frontline Indian Navy warship. The incident occurred while the Indian vessel was executing a routine surveillance mission.
According to Indian government sources, the Pakistani ship approached at high speed and executed a manoeuvre that New Delhi has officially termed “unprofessional and unsafe.” While contact was made between the two vessels, no major damage was reported to the Indian warship.
A Direct Violation of Bilateral Agreements
India has reacted swiftly and strongly to the provocation, describing the Pakistani conduct as completely unacceptable. The Ministry of External Affairs (MEA) pointed out that the actions of the Pakistani vessel were in direct violation of established bilateral protocols.
Specifically, the incident breached Article 10 of the 1991 India-Pakistan Agreement on Advance Notice on Military Exercises, Manoeuvres and Troops Movements. This technical safety measure explicitly requires naval ships and submarines from both nations to maintain a minimum separation distance of three nautical miles while operating in international waters. The rule was specifically designed to prevent exactly this kind of unintended collision or close encounter.
Diplomatic Fallout and Strong Protest
Following the incident, the diplomatic response from New Delhi was immediate. On September 16, India summoned the Charge d’Affaires of the Pakistan High Commission in New Delhi to lodge a formal and strong protest.
The Pakistani diplomat was explicitly advised to inform the relevant authorities in Islamabad that all military units must observe due care. India emphasized the necessity of respecting bilateral agreements to ensure such reckless incidents are not repeated. Furthermore, India’s Charge d’Affaires in Islamabad has been instructed to register a mirror protest directly with Pakistan’s Foreign Ministry.
The Broader Context: Strained Relations Post OP Sindoor
This maritime encounter cannot be viewed in isolation. It occurs against the backdrop of persistently strained relations following the military exchanges of Operation Sindoor in 2025.
While there has been no official statement from Pakistan’s Foreign Office linking this specific collision to broader military posturing, New Delhi views the incident as another example of reckless behaviour that risks unnecessary escalation. The Indian Navy continues its routine operations in the region unhindered. However, the government has made it abundantly clear that while it seeks to safeguard operational freedom in international waters, any such provocations will be met with a firm and uncompromising diplomatic response.
