Several dozen Libyans, flown to Greece for medical treatment and physiotherapy after the country's eight-month civil war, blocked traffic in protest in this northern city, after four people were injured in a hotel brawl.
Hospital and ambulance officials confirmed that four Libyans were being treated late Wednesday for minor injuries.
Police said the cause of the fight between the Libyans and other hotel guests remained unclear, and made no arrests. Traffic was blocked for about two hours before the protest ended peacefully.
Several hundred Libyan civil war victims are being treated in Greece.
