Petrol bombs have been thrown at police officers in Londonderry on the sixth consecutive night of violence in the city.
Makeshift barricades were also set on fire on a number of roads.
The attacks began early in the evening and continued into the early hours of Friday morning.
The petrol bombs were thrown towards police Land Rovers and at officers on the ground.
The makeshift barricades were built and set on fire on the Lecky Road flyover and on Fahan Street.
The PSNI said young children were among those involved in the trouble. Police closed sections of the walls overlooking the Bogside.

On Thursday night, BBC News NI’s Kevin Sharkey said that a large police presence, including officers in riot gear, had gathered around the city’s walls, while a crowd had also gathered in the Bogside.
SDLP leader Colum Eastwood said the violence was only succeeding in terrifying people in their own homes.
These people who are supposedly republicans, who are supposedly trying to get a United Ireland are destroying their area, he said.
Now, I don’t know how many times we have to learn this lesson that this does not work.
It’s not only morally reprehensible, it’s strategically stupid.
A Twelfth of July parade passed off peacefully in Londonderry earlier on Thursday, although police in riot gear separated a group of nationalists from the return parade as it made its way through the Diamond in the city centre.
The PSNI has said there have been two separate attempts to murder officers during the violence in the past week.
We regret to say that we are experiencing further disorder in the area of the Bogside with a number of petrol bombs already thrown at police. There is a large crowd gathering. It is clear that there are young children involved. Parents – make sure your children aren’t involved.

On Tuesday, police said dissident republicans were responsible for automatic gunfire directed at officers.
Then, on Thursday, the PSNI said two viable devices were thrown at officers on Derry’s walls.
PSNI Supt Gordon McCalmont described it as a reckless act that showed a blatant disregard for life.
