He announced this on his Twitter page.

“Our main priority is to ensure the safety of people, so I decided to extend the curfew until Tuesday. It will start at 20:00 local time, ”he said.

These protests have power and meaning. But as the night wears on we are seeing groups use them to incite violence and destroy property.

Our first priority is keeping people safe, so I'm extending the curfew to Tuesday. It will begin at 8pm.

The mayor indicated that this measure is connected with the fact that at night, against the background of protests, provocateurs are engaged in the destruction of other people's property and commit violent acts.

It was previously reported that New York State authorities are ready to engage the National Guard, if necessary, amid mass protests that began in the country after the death of African American George Floyd.
