I doubt the Pakistan navy would have had any idea who or what was on the boat , whether adrift or under power.
Had it been the case, the news would have been beamed by every Indian channel accusing Pakistan of not helping poor , innocent, harmless Indian fishermen and how India gave medical help to some Pakistani girl.....the usual
And we all remember live pictures being beamed into every household of the so called terror boat being followed and blown up......not to mention the farce that turned out to be.
Don't feed the ungrateful troll. I am certain that those rescued sailors are grateful to the Pakistani Navy.
