The United States imposes sanctions on Tanzania’s senior police official, citing alleged human-rights abuses linked to the detention of activists ahead of last year’s disputed presidential elections. Multiple outlets report that the U.S. Treasury, acting through the State Department’s process, sanctions the Tanzanian police chief and bars him from entering the United States. BBC and Bloomberg specifically describe allegations involving torture of detained human-rights activists, while other reports frame the action more broadly as violations committed by the police force. Free Malaysia Today and Bloomberg identify the sanctioned official as Faustine Jackson Mafwele, described as a senior assistant commissioner. The U.S. says it has credible information connecting him to the alleged abuses. The sanctions arrive amid ongoing international scrutiny of Tanzania’s human-rights record in recent years, with BBC noting increased attention to policing and treatment of detainees. The reports do not indicate that Tanzania has admitted wrongdoing, but they describe the U.S. action as a response to information about alleged conduct by senior security officials. The sanctions include financial restrictions and an immigration ban from the U.S.
