Vigilante group Republican Action Against Drugs (RAAD) has denied claims that it is targeting republicans.
In a statement, the group rejected reports that it had issued a warning to republicans following the shooting of two young men in the city last week.
Both men were from a prominent republican family and one is the son of a former IRA prisoner.
The vigilante group said its views had been misrepresented.
“At no point did we threaten any republican,” the RAAD statement said.
The issue arose after the father of one of the victims of last week’s shootings claimed that RAAD were “putting it up to republicans”.
The group said last week that children of republicans will not be exempt from their attacks because of who their parents are.
