Brother of Israeli hostage taken at Nova music festival still hoping for safe return

Trapped in the ruins of Gaza, there are at least 20 Israeli hostages who are believed to be still alive, held captive by Hamas.

One of them is Gal Dalal's younger brother, the now 24-year-old Guy Gilboa-Dalal.

"Every bomb, every military operation, everything that's going on, they're putting my brother in risk," Gal told CBS News.
