The PSNI has confirmed that a security alert in the Waterside area of Derry will continue into Tuesday evening.
A police cordon was established shortly after 7pm on Monday night after a "suspicious object" was found in an area in Corrody Road between its junctions with Strabane Old Road and Kittybane Road.
No homes have been evacuated as part of the operation so far.

Providing the latest update, Chief Inspector Michael O 'Loan said: “We know there is disruption to the community as a result of this incident, and we thank all those who are affected for their co-operation and patience as we work to make this scene safe.
"This area is used by local people, including dog walkers, and we ask that until the scene is declared safe, people heed the cordons we have in place in the area.
"I want to reassure the community we’re working through this situation as quickly as we can, and we will keep you updated with any developments.
"Our priority is everyone's safety and we will not take any risks with that."
Meanwhile, Sinn Fein councillor and the city's Deputy Mayor, Christopher Jackson, said dog walkers had come across the object when out walking.
"The people who left this object have absolutely no regard for the people of this area," he said.
"There was a Gaelic match going on when this was reported to the police and it was dog walkers who actually contacted me to say they had found it.
"This has caused vast disruption to the local community in a time when it's not needed.
"The police have told me that they expect that stretch of road to be closed for the rest of the day at least."
