The Jerusalem Post newspaper reported on Sunday that Ghaith had been arrested in the Beit Hanina quarter of Jerusalem while Faqih in a village, south of the city of Ramallah.
Ghaith’s lawyer told the newspaper that the governor had been accused of “threats” without going into further details.
The Palestinian Authority called the arrests of Ghaith and Faqih a “new Israeli crime against the Palestinian people.”
For decades, Israel has been in conflict with the Palestinians, who have been seeking diplomatic recognition for their independent state on the territories of the West Bank, including East Jerusalem, which are partially occupied by Israel, and the Gaza Strip.
The Israeli government refuses to recognize Palestine as an independent political and diplomatic entity and continues to build settlements in the occupied areas, despite objections from the United Nations.
