[Refugees and migrants, most of them Afghans, block the entrance of the refugee camp at the disused Hellenikon airport as police officers try to disperse them, in Athens]A group of migrants and refugees on Monday blocked a Greek minister from entering the former Athens airport terminal, where they have been stranded for months, in a protest against their living conditions. Dozens of protesters, among them many children, rallied outside a gate chanting "Go, Go!" and "Liar!" to Migration Minister Yannis Mouzalas. The government wants to clear out the entire compound, which consists of venues used in the 2004 Olympic Games and the former Athens airport, as Greece has agreed to lease it to private investors under its bailout programme.
