HYDERABAD: Sindhi Sangat Sindh Chairman Mansoor Khaskheli has demanded of the government for holding the upcoming population census in a transparent manner. He said that over four million illegal immigrants are living in Sindh. He said that illegal immigrants from Bangladesh, Iran, Afghanistan, India and Burma have got fake CNICs, violating the Citizenship Act of 1951. In this situation, the Sindhi speaking people might turn into a minority in the upcoming population census to be carried out next month, he feared.
