Sudan: Fear for safety/incommunicado detention/possible prisoners of conscience
Environmentalist Zahir Mohamed Musa was arrested by the security forces on 13 July in the town of Sinja in White Nile state, central Sudan. Two other environmentalists, Osman Ibrahim and Pakinam Saad Eddin, and another man, Mohamed Hajana, were arrested on 16 July by the security forces in Sinja. They are being detained at an unknown location and Amnesty International fears for their safety. The four men may be prisoners of conscience, arrested solely on account of their peaceful activities.
