Geo Films, which has the distribution rights for the film in Pakistan, had started publishing the release of the film with the note 'subject to censor clearance' but its release on December 22 is unlikely now.
The first part, "Ek Tha Tiger", was also not cleared for the release in Pakistan.
Sources said the Ministry of Information, Broadcasting, National History and Literary Heritage has refused to grant a No-Objection Certificate for the film upon CBFC's recommendation.
In the spy thriller, directed by Ali Abbas Zafar, Salman plays the role of a Raw agent who falls in love with Pakistani spy Zoya (Katrina) and together they team up to fight against terrorists.
