Petrol stations have run dry in Greece as a customs strike over government austerity measures began to bite.
Customs staff initially walked out for three days on Tuesday over salary freezes and cuts in bonuses.
But yesterday their union declared three 48-hour rolling strikes that will keep customs offices shut until next Wednesday, when all workers are being asked to join a general strike.
The customs walkout has hampered imports and exports, but the supply of fuel has been the most affected. Many service stations in Athens had run out of all fuel, while those still open were rationing supplies with a £20 limit per customer.
