A protest held by residents in south Belfast, following a spate of racist attacks on houses occupied by Romanians, was attacked on Monday night.
The demonstration was attacked by a group of young people, who came up a side street on the Lisburn Road throwing bottles and shouting abuse at the protestors.
Police are investigating racist incidents in Belgravia Avenue and Wellesley Avenue that occurred last weekend.
A local resident told u.tv that a gang of youths attacked the houses with bricks and smashed windows.
A PSNI spokeswoman said: "A crowd gathered on each occasion and the properties and a number of windows were smashed."
People living in the Lisburn Road have called on locals to demonstrate against the attacks on Monday evening.
Alliance Assembly member Anna Lo said: "These acts of intimidation and hate are utterly contemptible. I am outraged that individuals can bring themselves to carry out crimes of this nature."
"A few thoughtless thugs must not be allowed to disrupt people's lives and cannot be allowed to tarnish the good reputation of south Belfast."
"These thugs need to realise that it is people who carry out racist hate crimes who are not welcome in our society. People who can help police catch the perpetrators of these attacks must contact them immediately," she added.
