Some 30 prisoners, who have been on hunger strike for almost two months in Western Sahara, have agreed to take food again.
They ended their hunger strike because of their families' fears for their lives, the Moroccan Human Rights Association (AMDH) said. Most of the prisoners were arrested in the anti-Moroccan riots in May in the main Western Sahara town of Laayoune.
Morocco annexed Western Sahara in 1975, after colonial power Spain withdrew.
Moroccan claims of sovereignty are contested by an armed independence movement, the Polisario Front.
The UN-backed peace plan includes a referendum on self-determination for the Saharawi people, but Morocco has refused to accept any loss of control over the area.
AMDH spokesman Adelilah Benabdeslam said the prisoners might resume their hunger strike because the Moroccan authorities had not met their demands for improved conditions and to be moved to prisons closer to home.
