Indian and Pakistani naval vessels collide in the North Arabian Sea, prompting both countries to lodge formal diplomatic protests. India states that an Indian Navy warship was conducting routine surveillance in international waters when a Pakistani naval vessel approached and manoeuvred in an “unprofessional and unsafe manner,” leading to the collision. India says there are no reports of casualties or significant damage.

After the incident, India summons Pakistan’s senior diplomatic representative in New Delhi, describing the conduct as “unacceptable and unprofessional.” India also instructs its charge d’affaires in Islamabad to raise the issue with Pakistan’s foreign ministry. Pakistan’s response, reported by some outlets, includes calling in India’s diplomatic representative to register its own protest over the incident.

Some reporting links the episode to an April 1991 bilateral arrangement on advance notification for military exercises, manoeuvres and troop movements, with India saying the incident may relate to that framework. Outlets also note that details such as the specific vessels involved and the immediate circumstances before the collision are not fully established in the available accounts, and further information may follow from investigations or official statements.
