The Israeli army said Sunday it would impose a closure on the West Bank for the duration of Purim, as is standard practice during festivals and holidays.
The IDF said crossings into the Gaza Strip will also be shut during the closure period, between Tuesday night and Saturday night.
During the closure, exceptions will be made for humanitarian and other outstanding cases.
The move follows a review of the security situation and is dependent on government approval.
Purim starts Wednesday evening in most of the country, and Thursday evening in Jerusalem.
Jewish holidays are generally seen as times of increased tension, when the risk of terror attacks is higher.
Ordinarily, tens of thousands of Palestinians from the West Bank enter Israel and Israeli settlements for work each day. A far smaller number of Gaza residents also travel to Israel, mostly to receive medical treatment.
