The process of creation of the National Register of Citizens (NRC) is completely an "internal affair" of the Indian government and the cooperation between the border guarding forces of the two countries is very good, the chief of Border Guards Bangladesh (BGB) said here on Sunday.

The BGB will continue to work to prevent illegal crossings into India, its Director General Maj Gen Shafeenul Islam said at a press conference here.

"This is completely an internal affair of the Indian government," he said when asked to comment on the NRC issue.
