Mrs Long said the appearance of the flag off Island Street yesterday (June 30) added “an even more sinister edge” to recent race-related incidents in the city.
Mrs Long said she had received a number of complaints from constituents regarding the flags, which she has passed to the PSNI for action.
“Yet again we see those who wish to bully anyone different from them use flags and emblems to assert dominance and control over a community. To do so at all is to be condemned but to put up these flags in broad daylight shows just how brazen the culprits are.
“To use flags hailing a hate group such as the KKK is sickening and lends a further menacing element to recent events. It is essential that every right-thinking person unites against those who engage in racist, bigoted or otherwise intolerant behaviour and does so with consistency.
“It is also critical that the all-party talks this week stop ducking the issue of the use and abuse of flags and emblems for the purposes of intimidation, and face up to dealing substantively with this challenge to a shared future and to the rule of law.”
