Protesters wave their hands and sing in front of police as they block a street near the parliament in central Sofia November 13, 2013. Hundreds of students tried to blockade the Balkan country's parliament on Tuesday and force out the fragile government of Prime Minister Plamen Oresharski - under pressure from daily protests against alleged corrupt ties with business groups. A peaceful demonstration escalated late on Tuesday as some of the protesters threw bottles at heavily clad riot police and tried to break the metal fencing around the building.
