A security alert is continuing after suspicious objects were uncovered during a search in the Waterside area of Londonderry.
Army bomb experts are examining a number of suspicious objects
Police said the items found included coffee jar bombs, blast bombs, incendiary devices and pipes suitable for manufacturing pipe bombs.
The items were discovered in a garden shed at a house in Lincoln Courts on Friday.
Army bomb disposal experts are at the scene and residents have been moved from a number of houses in the area to a local community hall.
Meanwhile, a group is to be set up to help ease tensions in the Waterside following the fatal shooting of 22-year-old Darren Thompson on Wednesday.
He died in hospital on Friday after he was shot in the head as he walked to work along Woodburn Park in the Waterside area.
After the shooting, a number of items - which had been set on fire - were found in the Lincoln Courts estate.
DUP Assembly member William Hay said about 12 families had to move from their homes in Lincoln Courts as Army bomb experts examined the scene.
"People are annoyed, angry and upset that this type of violence has been visited on them," Mr Hay said.
He added that concerned people within the community met police on Thursday.
"There is a great lot of fear within the community," he said.
"It is important to get this group so that they can relay the deep concerns of people to the police."
