Khalida Jarrar, a member of the Popular Front for the Liberation of Palestine (PFLP), was arrested from her home in Ramallah city, according to her daughter.
“At least 10 Israeli soldiers raided the house at dawn, arrested my mother and took her to an unknown location,” her daughter Yafa said.
The Israeli army said Jarrar was detained on suspicion of violent public disturbances.
“Her arrest had nothing to do with her membership in the Palestinian Legislative Council,” the military said in a statement.
The PFLP, for its part, said Jarrar's detention "reflects the confusion of the Israeli occupation".
“The arrest follows a campaign of incitement launched by the Israeli government against PFLP and the resistance factions," it said in a statement.
Jarrar was released by Israel in mid-2016 after spending 15 months in prison.
According to Palestinian figures, Israel is currently holding more than 6,500 Palestinians -- including scores of women and children -- at 24 detention centers across the country.
