Pakistan's claim that Indian national Kulbhushan Yadav -- sentenced to death by its military court -- has refused review of his case and wants to appeal for mercy, is proof of its "reticence" to implement the order of the International Court of Justice in "letter and spirit", India said today. Calling Pakistan's move a continuation of the four-year-long "farce", the foreign ministry said the media statement "seeks to mask its continuing reticence".
