The videos focused on “severe restrictions” on press freedom in Turkey, Mexico and Egypt, and included comments from Russian and Pakistani journalists, said Alan C. Miller, the chief executive of the News Literacy Project. He said an alliance official first asked his group to delete the reference to Turkey, and then said that no clips could be presented.
Turkey is considered by many groups to be the world’s leading jailer of journalists, imprisoning dozens at a time.
Mr. Miller, who was to moderate a panel discussion that included well-known journalists and the representatives of several press groups, said he refused to make the changes sought by the United Nations Alliance.
“I could not permit this censorship of our presentation due to the stated concern that it would offend one or more countries engaged in repression and violence against journalists,” he said on the group’s website.
Farnaz Fassihi, a Wall Street Journal reporter who was to have been on the panel, called on Secretary General António Guterres to ask the alliance’s top official to resign.
