--
Greek riot police and protesters have clashed outside parliament during a mass rally taking place as part of a general strike.
Police fired tear gas Wednesday at scores of protesting youths, who hurled rocks and firebombs as running battles broke out.
More than 30,000 protesters had attended the rally, while the general strike halted public transportation and led to the cancellation of more than 100 flights at Athens International Airport, as unions stepped up opposition to the country's austerity measures.
