Ma'an- Israeli forces on Tuesday detained a prisoners' rights worker and confiscated his cell phone and computer, a detainees' center said.
The center said Sami Hussein, an employee in the Bethlehem-based organization, was detained during a raid on his home.
Hussein has been detained several times and has spent 20 years in Israeli prisons, the center said, adding that he had three children.
An Israeli military spokeswoman said 11 Palestinians were detained across the West Bank overnight.
