The October 7 concert was scheduled to take place on the second anniversary of Israel’s military offensive in Gaza.

For days, Turkish social media accounts and pro-Gaza NGOs had been calling for the event to be scrapped, accusing Williams of being “Zionist”.

The 51-year-old singer has faced renewed scrutiny in Turkey over his family’s Jewish heritage and his 2015 performance in Israel, which drew criticism from pro-Palestinian human rights groups.

Bubilet, the ticketing company, said it had cancelled the concert at the request of the Istanbul Governor’s Office.

The governor’s office was not immediately available for comment.

Williams wrote on Instagram late on Saturday that the safety of his fans “comes first,” adding he was deeply sorry for the cancellation, which he said was “beyond our control.”
