9 photos that show the tension in Greece right now

On Sunday, July 5, Greece will have a referendum on whether to accept an accord with its creditors. This weekend could be Greece's last chance to get a bailout, or possibly default to the International Monetary Fund.

Not only could this be catastrophic for Greece as a country, which also owes billions to the European Central Bank and European Commission, but it could be devastating for the Greek people, who are already limited to a maximum €60 (about US$67) ATM withdrawal in the wake of banks closing.

Everyone already seems to be under a tremendous amount of stress, as evidenced by recent pictures from overseas.

Greece closed down most of its banks on Thursday, fearing a rush of people trying to withdraw their money before the referendum. That hasn't stopped people from lining up to withdraw from the remaining open ATMs.
