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.

Dozens were arrested in Israel as protesters gathered outside politician's homes, military headquarters and on major highways to demand the Israeli government strike a deal for the release of hostages held in Gaza.

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.
