On March 20, about 5000 supporters of the Communist Party of Greece (ΚΚΕ)—mainly high school and university students[10]—protested outside the parliament building in central Athens against the government's support for the NATO-led intervention in Libya. They carried anti-government banners and placards that read "The imperialists out of Libya" and "US-EU-NATO kill people", shouted anti-intervention slogans and torched the flag of the European Union.[11][12]
