A group of more than 140 Palestinian police officers have arrived in the Gaza Strip from Algeria.
They are scheduled to join a contingent of 12,000 Palestinian police officers who will be on patrol in the West Bank when Palestinian self-rule is extended in the area.
Israel Radio reported that two members of the newly arrived police force were stopped by Israel for security reasons.
Meanwhile, Israel extended its closure of Gaza from Wednesday to Thursday.
The closure was imposed last week, and extended several times, amid reports that a terror attack was being planned to thwart the still-evolving agreement to extend Palestinian autonomy in the West Bank.
