Pakistan has ordered a U.S.-based website propagating the faith of Pakistan’s minority Ahmadis shut down over allegedly blasphemous content, one of the site’s managers said Thursday.

Harris Zafar said Pakistan’s Telecommunication Authority earlier this month issued a legal notice for him and fellow American Amjad Mahmood Khan, who also manages Trueislam.com, demanding that the site be shut down.

Zafar said the website is based in the U.S., where both he and Khan live and work, and called Pakistan’s action “a brazen act of suppression of freedom of expression and freedom of religion.”
