Police said they were treating the attack as sectarian.
SDLP councillor Declan O'Loan said the attack showed "that the conditions exist in Ballymena for something like this to happen at any time".
"These underlying conditions must be tackled. All politicians have a clear and urgent responsibility to do this," Mr O'Loan said.
Sinn Fein assembly member Philip McGuigan also condemned the attack.
"I have always said that political leadership, particulary from within the unionist community, is needed to bring this to an end, and that is still quite clearly lacking," he said.
Police have appealed for anyone with any information to contact them.
