India rejects Pakistan's allegations over Arabian Sea ships collision
India on Friday rejected Islamabad's allegations over the collision between a Pakistani vessel and an Indian Navy warship in the Arabian Sea. MEA spokesperson Randhir Jaiswal called Pakistan's response "the usual prevarication". He said PNS Hunain's dangerous overtaking manoeuvre on September 15 violated Article 10 of the 1991 India-Pakistan agreement, which bars naval units from coming within three nautical miles. INS Kolkata suffered no major damage and remains at sea. Pakistan had alleged provocative Indian action in its Exclusive Economic Zone.

Analysts’ view opinion
This is not merely a collision at sea — it is the latest chapter in an ongoing political and diplomatic contest between the two capitals. India's strategy is clear: anchor the argument in rules by citing Article 10 of the 1991 agreement and international collision-prevention regulations, while simultaneously signalling de-escalation by stressing that INS Kolkata suffered no major damage and remains at sea. Pakistan's counter-narrative — that an Indian vessel acted provocatively inside its Exclusive Economic Zone — shows both governments positioning themselves as the aggrieved party for their own domestic audiences.
- Summoning the Pakistani Chargé d'Affaires and then dismissing Islamabad's reply as "the usual prevarication" is calibrated pressure: sustained diplomatically, deliberately not escalated militarily.
- By naming a specific treaty article and the three-nautical-mile rule, India shifts the dispute from political accusation to documented rule-violation, which strengthens its hand in international conversations.
- The line that there was no major damage and the ship remains deployed serves two audiences at once — domestic reassurance about naval capability, and an external signal that New Delhi is not seeking escalation.
- With both sides offering flatly contradictory accounts of the same night, and no independent verification cited, this is likely to remain primarily a narrative contest.
- Any repetition of such incidents in the Arabian Sea would increase political pressure on a government already committed to a firm public posture on Pakistan.
What to watch — Watch whether Pakistan takes the matter to international forums, whether India releases further detail or evidence, and above all whether such close encounters recur in the north Arabian Sea.
The story rests on competing official statements about how the collision occurred and who was at fault; it does not establish independently verified facts, the full extent of any damage, or what either side will do next.

Context
On the night of September 15, 2026, a Pakistan Navy ship, PNS Hunain, collided with the Indian Navy's frontline warship INS Kolkata in the north/western Arabian Sea while the Indian vessel was on a routine surveillance deployment, according to the Indian side. India summoned Pakistan's Chargé d'Affaires on September 16 and lodged a strong protest over the Pakistan Navy vessel's "unacceptable conduct". Pakistan countered that the incident followed a "highly provocative and unacceptable action" by the Indian vessel inside Pakistan's Exclusive Economic Zone. On September 18, the Ministry of External Affairs rejected Islamabad's allegations, citing violations of a 1991 bilateral agreement and international collision-prevention rules.

Who has a stake
- Ministry of External Affairs, India — Lodged the protest and publicly rejected Pakistan's allegations; manages the diplomatic response and messaging.
- Indian Navy / INS Kolkata — Its frontline warship was involved in the collision while on routine deployment; no major damage reported and it remains at sea.
- Pakistan Navy / PNS Hunain — Accused by India of an unprofessional and dangerous overtaking manoeuvre violating bilateral and international rules.
- Pakistan Foreign Ministry — Alleges provocative Indian action inside Pakistan's Exclusive Economic Zone; defending its account of the incident.
- Pakistani Chargé d'Affaires in New Delhi — Summoned by India to receive the formal protest, reflecting the downgraded diplomatic channel between the two states.
- Randhir Jaiswal, MEA spokesperson — Articulated India's official position at the regular media briefing.
Why it matters
A physical collision between warships of two nuclear-armed neighbours, followed by contradictory official accounts, carries real escalation risk in a crowded and strategically vital sea lane. India's invocation of the 1991 bilateral agreement shows that confidence-building measures from an earlier era remain the main guardrail even when broader diplomatic ties are thin. How such incidents are handled at sea and in diplomatic channels determines whether an accident stays an accident.

Prelims pointers
- Agreement between India and Pakistan on Advance Notice on Military Exercises, Manoeuvres and Troops Movements was signed in April 1991.
- Article 10 of the 1991 agreement bars naval units at sea from coming within three nautical miles of each other.
- INS Kolkata is a frontline Indian Navy warship; PNS Hunain is the Pakistan Navy ship involved in the September 15, 2026 collision.
- International Regulations for Preventing Collisions at Sea (COLREGS) govern conduct of vessels to avoid collisions.
- Exclusive Economic Zone (EEZ) was the basis of Pakistan's counter-allegation against the Indian vessel.
- India conveyed its protest by summoning Pakistan's Chargé d'Affaires, not an ambassador or high commissioner.
Mains framing
The Arabian Sea collision of September 15, 2026 between INS Kolkata and PNS Hunain illustrates how naval confidence-building measures, rather than political dialogue, now carry the weight of India-Pakistan crisis management. India's case rests on two legal planks: Article 10 of the April 1991 bilateral agreement on advance notice of military exercises, manoeuvres and troop movements, which mandates a three-nautical-mile separation between naval units, and the International Regulations for Preventing Collisions at Sea; Pakistan's counter-claim frames the encounter as provocative Indian activity within its Exclusive Economic Zone, a dispute over rights of navigation and surveillance in another state's EEZ. The immediate implications are escalation risk in a busy sea lane, the absence of full diplomatic representation (the protest had to be delivered to a Chargé d'Affaires), and the reliance on "advisories" rather than any verification mechanism. A grounded way forward, consistent with what the source supports, lies in strict observance of the 1991 agreement and COLREGS by all military units, professional conduct at sea, and use of existing bilateral channels to prevent repetition — as India itself advised Pakistan.
