Two yeshivas will shut down amid a coronavirus spike in several neighborhoods in southern Brooklyn.

The city declared this area a coronavirus cluster site, accounting for 20 percent of all new cases over the last week.

"We've shut down two yeshivas, no one wants to shut down the yeshivas. That's never something we want to do but the health department deemed it was necessary and if others have to be closed they will be. And any situation that's not safe has to be addressed," de Blasio said. "I think the outreach efforts have been consistent. I think the challenge as with everyone everywhere is over months and months, of course, there's some fatigue in every community about being constantly asked to follow these rules but we have to keep redoubling the effort."

The city said it's now ramping up education and enforcement in southern Brooklyn, and specifically warns against large indoor gatherings.
