The signs, saying certain people are no longer welcome there, have been reported to the PSNI, the Department for Communities and the Housing Executive for immediate removal.
Kate Nicholl MLA said: “I am shocked by the erection of these signs and posters. They are designed only to divide communities and stir up fear. They create a chill factor for those living in the area and badly damage community relations.
“It is also important we don’t fall for the right-wing media narrative of pitting vulnerable people against one another. I work with refugees every single day and what they have endured is incomprehensible to most of us. They are people - just like anyone else - who have value and who matter. Seeking a safe and peaceful life is not a crime, it is a human right. No human being is illegal.
“Take the time to get to know your neighbours, check in on those who may look or sound different to you. They may be fearful and we need to reassure them they are welcome and valued in Northern Ireland.”
Paula Bradshaw MLA added: “The posters and those who put them up do not represent South Belfast, which is a kind, compassionate, and welcoming constituency. There are real issues in terms of housing shortages, but that is not the fault of vulnerable people.
“We urgently need to get back into a functioning Executive and work together to ramp up the building of new homes to ensure all have equal access to housing in Northern Ireland.”
