The Indian navy has denied reports that a deal has been finalised with Russia for the lease of an Akula-class nuclear-powered submarine.
Navy spokesman, Commander Vinay Garg, told the BBC talks were continuing between the two countries but no agreement was completed.
He said more details could be expected by Monday.
Earlier reports from Moscow claimed India had reached agreement to lease the submarine for 10 years.
The reports said the deal was worth tens of millions of dollars.
The Akula is a sophisticated nuclear-powered submarine that would significantly increase India's naval reach.
