The west Belfast home of Sinn Fein President Gerry Adams has been attacked, the party has said.
Sinn Fein President Gerry Adams's home was attacked
The party said the homes of two other Sinn Fein members, Fra McCann and Chrissie McAuley, were also targeted in ball bearing attacks on Wednesday.
The party's general secretary, Mitchel McLaughlin, said they believed the attacks were linked. No-one was hurt.
Police have said anyone with information about recent vandalism in the area should contact them.
"This wave of attacks replicates similar incidents last year when dozens of republicans' homes were targeted in Belfast," Mr McLaughlin said.
"It is clear that all of the attacks last night were linked and those responsible were operating with accurate information regarding the addresses of republicans. One source of this information could obviously be the PSNI.
"Thankfully nobody was physically injured and I would urge republicans to be vigilant in the coming period."
A Police Service of Northern Ireland spokesman denied any suggestion that information assisting the attackers came from the police.
"We totally refute this unfounded allegation.
"Our job is to make west Belfast safer for everyone and we abhor incidents such as this where property belonging to anyone is damaged," he said.
He said anyone with information about recent vandalism in west Belfast should contact the police, and added that officers could offer crime prevention advice to anyone who had property damaged.
