Sinn Féin Lisburn Councillor Sue Ramsey has expressed concern and warned residents in west Belfast to be vigilant after her home, along with another in Twinbrook, was attacked on Friday night.
There is mounting suspicion among republicans that such attacks would not be possible without the active assistance of elements within the PSNI police.
Councillor Ramsey said: ``In the past number of weeks the homes of a number of republicans have been targeted. These high velocity ball bearing guns that have also been fired at people walking in and around west Belfast are capable of causing serious injury.
``The targeting of the homes in well over a dozen attacks in the past two weeks across West Belfast suggests that there is a degree of co-ordination and planning as well as specific knowledge.''
Loyalists have also been blamed for a weekend pipe bomb attack in the Waterside area of Derry. The device was thrown into the house after a window was smashed with a brick.
Another window at the rear of the house was smashed when the device exploded. Shrapnel damage was also caused. There were no injuries.
