Greece was hit by a public transport strike on September 22 against a new wave of austerity measures proposed by the government.
On September 21, the government announced fresh cuts in pensions and tax exemptions. It also suspended thousands of state employees as it seeks to persuade the European Union and the International Monetary Fund to release the next tranche of a 110 billion euro package of loans to help Greece avoid defaulting on its huge debts.
The capital Athens was brought to a standstill as the metro, trams, trains, buses and taxis all stopped work.
Flights were also delayed or cancelled by a four-hour walkout by air traffic controllers. Private and public sector trade unions have announced more strikes next month.
