Narrative:

Flew into embedded thunderstorm. Radar did not show any returns. Approximately 5 flight attendants suffered minor injuries. Same number of passenger injured. Most serious was head cut requiring 6 stitches. Callback conversation with reporter revealed the following information: the reporter stated 5 flight attendants were injured as they were thrown against the ceiling while they were serving. The food cart was also thrown against the ceiling. This captain is an instructor pilot with the airline and has never had an upset or turbulence encounter of this magnitude. The first officer was just commenting as they were scanning the radar that it looks like the WX is behind. There was no warning. The whole event only lasted for less than 5 seconds maximum.
