A national day of action is underway in Israel - organised by the families of captives still held in Gaza. The mass action is expected to shut down schools, businesses and public transport across the country. Several rallies are planned, including a big demonstration in Tel Aviv. Protesters say they want to pressure the government into signing a Gaza ceasefire and captive release deal with Hamas. They fear Prime Minister Benjamin Netanyahu's plan to seize Gaza City will endanger the lives of their loved ones.
