A chief superintendent in the police's Northern District said the preparations were designed with lessons learned from the deadly events last year.

Thousands were expected to arrive at the castle. UNIFIL was also said to be conducting patrols and monitoring activity along the northern side of the border.IDF Chief of General Staff Benny Gantz toured the West Bank and Syrian border Friday morning ahead of the planned protests. The IDF predicted protests in several Palestinian cities in the West Bank and at the Kalandiya crossing to Ramallah, north of Jerusalem. Officers from the Civil Administration contacted their Palestinian counterparts earlier this week in an effort to contain the protests and prevent them from escalating.As part of preparations in the capital, police said they would limit the access of Muslim worshipers to the Temple Mount for Friday prayers. Only men over the age of 40 in possession of a blue Israeli identity card and women will be given access to the Temple Mount on Friday, in an attempt to limit disturbances.Thousands of police officers will fan out across Jerusalem, with an emphasis on the alleyways of the Old City and crossings into the West Bank including the Rachel checkpoint to Bethlehem, said Jerusalem Police spokesman Shmuel Ben-Ruby.At the Kalandiya checkpoint Palestinian protesters were clashing with Israeli forces, throwing rocks, firebombs and burning tires. Security forces were using large amounts of tear gas, stun grenades, sound weapons and foul-smelling water to disperse the protesters.A large number of protesters arrived at the checkpoint from Ramallah.
