Families of three detained on Gaza flotilla deeply worried

The families of three New Zealanders detained as part of the Gaza protest flotilla say they deeply admire them - but are also deeply worried. Youssef Sammour, Rana Hamida and Samuel Leason were detained by Israeli troops last week after their boat tried to cross an Israeli blockade of Gaza as part of an international flotilla. Their families have been speaking at a media conference today, calling on the government to help them and their cause. Rowan Quinn reports.
