Large groups of youths have been throwing fireworks, bricks and bottles at police in Edinburgh, during a night of disorder across the city.
Video posted online shows officers responding to Bonfire Night incidents in the Sighthill, Niddrie, Gracemount and Gilmerton areas.
Riot police have been seen on the streets of Edinburgh, wearing helmets and carrying shields, as fireworks were lit and exploded around them.
One police officer has been injured after a brick was thrown through the window of her patrol car. One person has been arrested in connection with the incident.
Footage from Gilmerton, a suburb in the southeast of the city, also showed burning debris in the street as youths rode on bicycles.
Police were given extra stop and search powers in certain areas following "intelligence" about planned disorder and firework-related crime.
Superintendent Neil Wilson said: "We are currently responding to incidents of disorder involving large groups of youths throwing a range of objects, including fireworks, bricks and bottles, across Edinburgh."
A helicopter was also deployed as part of Operation Moonbeam, aimed at supporting local police in tackling fireworks-related offences.
Meanwhile Lothian Buses withdrew all services from the Niddrie area for safety reasons.
Niddrie was also the scene of disorder on 31 October, when police and public transport vehicles were pelted with fireworks and bricks.
On Tuesday, officers in Glasgow seized a "significant quantity" of fireworks from a van in the Drumchapel area which it is alleged were being "sold to the general public, including children".
There have been pockets of disorder in the city, with fire appliances being attacked, although injuries have been reported.
