Bhopal, Feb 22 (ANI): Vishwa Hindu Parishad (VHP) leader Ashok Singhal on Saturday said that of late a major concern that has come up in front of them is the decreasing number of Hindus and that unless conversions were stopped immediately, the day would not be far off when Hindus would be reduced to a minority in this country. Addressing a press conference, Singhal said it has become "imperative" for each Hindu couple to have five children.
