Greek rioters and protesters clashed with police Monday as they rallied to commemorate the death of 15-year-old Alexandros Grigoropoulos, killed by police during a protest two years ago.

The dramatic video shows protesters hurling rock and fire bombs at police, setting cars on fire, and even using metal pipes ans street signs to attack police.

The news agency Russia today describes the protests as the "worst riots in a decade," and said more than 40 youths were arrested while at least five people were injured. One of those included a bystander who was hit in the face with a rock.
