NOEL KING, HOST: We have entered into day six of a rescue operation in Surfside, Fla. Eleven people are now confirmed dead. And around 150 people are still missing. Rescue workers from Israel and Mexico have joined the search. NPR's Jasmine Garsd is in Miami Beach. She's been talking to responders. Hi, Jasmine. JASMINE GARSD, BYLINE: Good morning. KING: What's the mood like at the site of the collapse? GARSD: Well, there is a mix of optimism and hope. You hear it all day long from local officials and search crews. But at the same time, you also sense that reality is setting in for some people. As you say, there are about 150 people that are, quote, "unaccounted for." And complicating the search efforts are thunderstorms and the stifling heat.
