Kerry-Ann Brown said that she fears for the safety of her children - whose ages range from two to 10 - and has been left wondering what the future holds for them as an ethnic minority living in Northern Ireland.A brick was thrown through the window of the property at Linford Green at about 2.10am on Friday, while Ms Brown and her children were asleep inside."It is very stressful - it is a very stressful time," she said.Ms Brown came to Northern Ireland in 2002, and her children were all born in the region.She has lived in Rathcoole, Newtownabbey for a year with her family, but said she no longer feels safe.It's a fearful experience - a very depressing and sad one as well especially with children in the house because what do I tell the children?Kerry Ann BrownMs Brown said that in the past her two eldest children have arrived home from school telling her they had been called a racist name and wanting to know its meaning."Ten months ago, there was graffiti on my door. I called my landlord, we cleaned it off and that was it."If in 10 months it has escalated from graffiti to a broken window, what will happen next?"It is not right for me to live in fear - it is not right for my children to live in fear.Kerry Ann BrownDescribing how she feels, she said: "I don't think sad is the right word. I can't find a word to describe it - it's worrying."My children are all born here - they are black...what sort of future is there here for them then if this is happening? What sort of future is there for them?"We are human beings no matter what colour our skin is."Northern Ireland Secretary of State Theresa Villiers has condemned the attack."Like all right thinking people in Northern Ireland I am shocked by the latest in a series of racially motivated attacks. There is no place for such behaviour in modern NI," she said.Police are treating the incident as a hate crime and are appealing for anyone with information to come forward.
