Athens, Greece (CNN) -- The Greek capital was tense Thursday after the government ordered truck drivers back to work following a three-day strike.
Striking workers threw rocks and plastic bottles at the gates of the transport ministry in the morning, and police used tear gas to disperse the angry crowd.
The strike has caused gas stations in Athens to run out of fuel, stranding people around the country just as many Greeks leave for August vacation.
Bookings by tourists from neighboring countries were also "frozen" because of the strike, the head of the Hellenic Hotels Federation, Andreas Andreadis, said in a television interview Thursday.
Thousands of tourists from Russia, Bulgaria, and Serbia, who are traveling by car, remain stranded in northern Greece because of the strike, Andreadis said.
