RAMALLAH, Jan. 22 (Xinhua) -- Israeli forces have arrested eight Palestinians during an overnight arrest campaign in the West Bank, Palestinian sources said on Monday.

A lawmaker was among the arrested for several hours and was later released.

Palestinian parliament member and former Palestinian National Authority (PNA) Minister Omar Abdelrazeq, who belongs to Islamic Hamas movement, was arrested from his home in Salfit city north of the West Bank.

Abdelrazeq was released from Israeli jails two months ago. Palestinian sources close to the Hamas leader said this overnight arrest came for interrogation.

Currently, Israel withholds 10 Palestinian lawmakers in Israeli jails, most of whom are under administrative detention.

Administrative detention allows Israeli authorities to detain prisoners without trial. It is usually based on secret information that cannot be accessed by either the detainees or lawyers.

The detention could last for six months and can be renewed for unlimited times.
