"Under a three-month pilot project, Palestinians who work in Israel will, starting today, need to return home by the same crossing without taking buses used by (Israeli) residents" of the occupied West Bank, the official told AFP.
Hundreds of Palestinians travel each day to work in Israel from the occupied West Bank, mainly in the construction business, using travel permits each time they cross.
The official, who declined to be named, said Palestinian workers would now need to change buses to avoid riding vehicles carrying Israelis after crossing back into the West Bank.
Israeli settlers in the West Bank have called for years for Palestinians to be banned from public transport there, arguing their presence poses a security risk.
