Israeli actress Gal Gadot embraces hostage families at Tel Aviv square, meeting with wives and mothers of those abducted during the Oct. 7 Hamas attack.

Groups representing families of hostages organized the demonstrations as frustration grows in Israel over plans for a new military offensive in some of Gaza's most populated areas.

Large crowds of Israelis took to the streets on Sunday, launching a nationwide grassroots strike and widespread protests to demand the government secure the release of 50 hostages still in Gaza.
