At least 45,000 people participated in Sunday’s “flag march” in Jerusalem to mark Jerusalem Day.

Some 1,700 police officers are guarding the controversial event, during which marchers traditionally pass through the city’s Muslim Quarter, often triggering clashes with local Palestinians.

On Sunday morning, hours before the event started, Israeli right-wing activists clashed with members of the Islamic Waqf near the al-Aqsa Mosque.

The participants entered Jerusalem’s Old City through Damascus Gate and walked all the way to the Western Wall, where the event was concluded with a ceremony and prayer service.
