Greek railway workers and journalists have joined a wave of strikes against austerity measures imposed to prevent the country defaulting on its debts.
Strikes also kept island ferries in port for a second day today, while rotting mounds of rubbish remained uncollected for the 17th day in the country's cities.
Strikers include tax collectors and lawyers. Civil servants are occupying the finance and labour ministry buildings.
Unions have also called a 48-hour general strike, which will culminate on Thursday, when the Greek parliament votes on measures including further pension and salary cuts, and the suspension on reduced pay of 30,000 public servants.
Meanwhile, European countries are working to find a solution to the continent's debt crisis in time for a Sunday summit.
