The closure of one of Zambia's main independent newspapers is a "ploy to silence the media" ahead of the August election, Amnesty International said Wednesday.
The Post was closed down Tuesday on the grounds that it had more than 4 million dollars in tax arrears.
"If the newspaper owes taxes, necessary arrangements should be made to settle the dispute. Shutting down the newspaper threatens the right to freedom of expression," the rights group said.
Post editor in chief Fred M'membe Wednesday said the newspaper's taxes were "up to date."
"It is not money they are after," M'membe added. "What is happening now is discrimination on the basis of our editorial policy and our political views, our independent views."
The newspaper had been critical of President Edgar Lungu, who is seeking re-election.
