A truck loaded with weapons and hand grenades has plowed through a crowd of people on a sidewalk in the French resort city of Nice during Bastille Day, killing at least 80 people. Local officials say the truck was on the sidewalk for more than a mile before police killed the driver.  Anti-terrorist investigators have taken over the case.

On The 21st: As the world reacts to the most recent terrorist attack in the southern French town of Nice, we speak to a Nice native who’s recently relocated to Illinois. We also continued our summer books series with a talk about science and science fiction books with science communicator Joanne Manaster and Chicago sci-fi writer Marcus Sakey. Plus, we spoke with Savoy resident Betty Esser, who turned 102 this week.
