Because of an editing error, an article on Sept. 17 about an assertion by Edward J. Snowden, the former American intelligence contractor, that his leaking of documents about surveillance programs had improved individual privacy in the United States referred incorrectly to the revocation of his passport in 2013. It was revoked while he was in Hong Kong, not after he had traveled to Moscow.

Because of an editing error, an article on Sept. 14 about a denunciation by Zeid Ra’ad al-Hussein, the United Nations high commissioner for human rights, of what he called efforts to stop the United Nations Human Rights Council from monitoring abuses misidentified the agency that he leads. It is the Office of the High Commissioner for Human Rights, not the Human Rights Council.
