Einav Tzangaukar, whose son Matan is being held hostage by Hamas in Gaza, said at a Tel Aviv University conference that 'this government has no mandate to make any decision except to bring everyone back. A black flag waves over this government. If you don't rise up to fight alongside us for citizens' lives - we will hold you accountable when the time comes, this will not pass in silence.' The audience chanted: 'Everyone now.' Tzangaukar then declared that 'the only way to rehabilitate the country is to send the government and its leader home.'
