ATHENS, July 5 (Reuters) - Greeks cannot withdraw cash left in safe deposit boxes at Greek banks as long as capital restrictions remain in place, a deputy finance minister told Greek television on Sunday.

Greece’s government shut banks and imposed capital controls a week ago to prevent the country’s banks from collapsing under the weight of mass withdrawals.

Deputy Finance Minister Nadia Valavani told Alpha TV that, as part of those measures, the government and banks had agreed at the time that people would also not be allowed to withdraw cash from safe deposit boxes.
