Israeli forces have detained the wife of an Islamic Jihad leader who is being held in administrative detention, Israeli and Palestinian sources said on Monday.
Palestinian security sources in the northern city of Jenin said Nawal Saadi, 52, was arrested at her home in the city's refugee camp in the early hours of Monday morning.
An Israeli army spokeswoman confirmed the arrest.
"She was arrested this morning by border police and transferred to the custody of security forces, Israeli police, for questioning," she said.
There were no details on why Saadi was arrested. Her husband Bassam Saadi, a local Islamic Jihad leader, has been detained without charge by Israeli authorities for more than a year under an administrative detention order.
Israel regularly carries out arrest raids throughout the West Bank, including in areas under full Palestinian security control.
Last week, troops arrested five Palestinians, including two men with ties to the Islamic Jihad movement.
