India summoned the Charge d’Affaires of Pakistan’s High Commission in New Delhi to the Ministry of External Affairs (MEA) on Wednesday (September 16, 2026) and lodged a strong protest over the “unacceptable” and “unprofessional” conduct of Pakistani naval units at sea, which resulted in a collision with a unit of the Indian Navy.

The collision occurred on the evening of September 15, 2026, when a Pakistan naval ship came close to a frontline Indian naval warship that was on a routine surveillance mission in the North Arabian Sea. The Pakistani vessel manoeuvred at high speed in an unprofessional and unsafe manner, leading to the collision, sources said. No damage has been reported.

“While the incident, which took place in international waters, did not cause any major damage, the conduct of the Pakistani naval ship was in direct contravention of Article 10 of the Agreement between India and Pakistan on Advance Notice on Military Exercises, Manoeuvres and Troops Movements of April 1991,” the MEA said in a statement.

“The Charge d’Affaires of Pakistan was advised to convey to the concerned Pakistani authorities, the need for all military units to observe due care and respect the provisions of the relevant agreements between the two sides in order to prevent any repeat of such incidents.”

The Charge d’Affaires of India in Islamabad has also been instructed to lodge a similar protest with the Ministry of Foreign Affairs of Pakistan.
