so many apartments, as you mentioned, multiuse buildings. we have also learned at least one school in the area, not nearby, has been told to shelter in place. we are going to work some more information and find out about other areas schools. we have our man on the ground. john berman is in harlem and can tell us what he knows live from the scene. can you hear us? >> reporter: micayla, we were just told by the nypd, 1644 park avenue appears to not be there anymore. it just simply appears to be gone. there is so much smoke out here. it is spanning for blocks and blocks. you have people wearing masks to protect themselves from inhaling it. it is very dangerous, i imagine, to get too close without the mask. we are a safe distance right here, about a block and a half away.
