A group of around 100 protesters threw firecrackers, smoke bombs and bottles at police after breaking away from the main body of a demonstration in the Olympic host city of Milan on Saturday (Feb 7), Reuters reported. 

Police in riot gear and with shields responded with water cannon to try to disperse the group, some of whom wore hoods and scarves to cover their faces. Order was restored after a few minutes.

Six people were detained during the skirmishes, police sources said, according to Reuters. 

An estimated 10,000 people had taken to the streets of Milan in a protest over housing costs and environmental concerns on the first full day of the Milano Cortina Winter Olympics.
