In this letter Amnesty International urgently raises the case of Sayed Nazar Alwadaei, Hajar Mansoor Hasan and Mahmood Marzooq Mansoor with the Government of Bahrain ahead of the verdict in their criminal trial on 30 October 2017. These three individuals are relatives of Sayed Ahmed Alwadaei, a Bahraini human rights defender based in the United Kingdom, and his wife Duaa Alwadaei. The organization believes that Mr Alwadaei’s relatives are being prosecuted solely as a reprisal against him and the trial forms part of a pattern of harassment against his family.
