One, Amir Suliman, was arrested and released the same day. Abdelmoneim Aljak was released early the following morning but re-arrested on November 26, and Osman Hummaida, who is British, also remains in custody. The security service has not charged any of the men with any crime, though they have continued to question only of their human rights activities.

Sudanese authorities have not said on what basis the three were summoned or detained, but they are active in the Sudanese human rights movement and have participated in awareness-raising campaigns on justice and accountability, as well as highlighting the ongoing human rights situation in Sudan.

The three men were summoned by the political affairs section of NISS, which deals with civil society organizations and political parties. All three have previously been detained on several occasions because of their human rights activities.

“The Sudanese government is well-known for having little tolerance for criticism,” said Georgette Gagnon, Africa Director at Human Rights Watch. “This is part of a wider pattern of trying to silence those who support justice and to suppress information about the human rights situation in Sudan.”

Over the last year, the Sudanese government has increasingly targeted those who have spoken out about human rights abuses, the situation in Darfur, or international justice. This harassment intensified considerably following the May 10 attack by the rebel Justice and Equality Movement (JEM) on the capital and the announcement by the prosecutor for the International Criminal Court on July 14 requesting an arrest warrant for President Omar al-Bashir for war crimes, crimes against humanity and genocide. Journalists trying to publish articles about the situation in Darfur or the May 10 events and staff members of national NGOs working on these issues have been summoned and forced to censor any articles regarded as critical of the authorities.

Hummaida and Aljak work as consultants to civil society and nongovernmental organizations (NGOs). Suliman is chairperson of the Khartoum Centre for Human Rights and Environmental Development (KCHRED). The three were summoned by the National Intelligence and Security Services (NISS) political section in Khartoum North at around noon on November 24.
