Athens (AFP) - Greek Prime Minister Alexis Tsipras said Tuesday that the country's banks may not reopen until a hard-won bailout deal with the eurozone is finalised, a process that could take at least a month.

"The reopening of the banks depends on the sanctioning of the deal, which will take place in a month," he said in an interview on public Greek television, adding that he hoped in the meantime that the European Central Bank would raise the level of emergency liquidity assistance for the banks.
