Republicans commemorating the Easter Rising have been blamed for a paint and petrol bomb attack that permanently damaged an Orange hall in north Belfast.
The hall on Clifton Street was targeted at 10pm on Sunday - the same day as an uprising parade - with police officers also being attacked by a gang of up to 20 stone-throwing youths.
Hall curator Ronnie McDowell said he feared the attack would provoke Protestants to retaliate.
"The building is made from porous limestone, so the paint soaks into the walls," he added. "We'll never get rid of that.
"This was an unprovoked attack. There was nothing in the pipeline in terms of parades. The only thing we can tie it in with is the 1916 commemoration parade."
Sinn Fein condemned the attack.
