Protesters have clashed with Turkish police in Istanbul, after riot squads used tear gas and water cannon to eject demonstrators from Gezi Park.
The protesters quickly fled the park, but later erected barricades across nearby streets and lit bonfires.
Witnesses said it was one of the worst nights of unrest since the park was occupied 18 days ago.
