Background: The government of Pakistan has announced that it is refusing payment on all 100 and 500 rupee notes marked "Joy Bangla" or similar expressions.

The government said it would pay out on the notes if holders could prove it was legally obtained, and if they deposited the bills, with declarations, in their local banks before Thursday (June 10).

The government in Karachi said that large quantities of notes had been illegally removed from government treasuries, branches of the State Bank of Pakistan, and from offices and branches of other banks in east Pakistan.
