Protests worldwide feb 20 2013 6

Members of a Greek Communist trade union demonstrate on February 20, 2013 in the center of Athens against austerity measures. Greece was hit by a new strike on February 20 called by leading unions against unrelenting austerity in the recession-weary nation ahead of an audit by international creditors, disrupting flights, ferries and hospital services. The strike -- the first general work stoppage in debt-crippled Greece this year -- has forced airport authorities to scrap or reschedule dozens of flights while hospitals were operating on reduced staffing.
