Greece debt crisis: PM Tsipras defiant as bank controls bite

Greece's Prime Minister Alexis Tsipras has made a defiant speech as cash withdrawal limits begin to bite for Greek bank customers.
Mr Tsipras promised Greeks their pensions and wages would be safe.
Earlier he put new proposals in a letter to eurozone partners, accepting most of what was on the table before talks collapsed, but with conditions.
Germany says talks with Greece will not be possible until after a referendum called by Mr Tsipras for Sunday.
