The Ulster Defence Association - the largest paramilitary force in Northern Ireland - is imploding this weekend as it embarks on its third internal feud in six years.
Activists close to ousted North Belfast commanders Andre and Ihab Shoukri were engaged last night in a dangerous standoff with the UDA leadership following the expulsion from the organisation last week of both brothers, along with a key ally from North Belfast.
Extra police and troops have been drafted into the Shoukris' strongholds, the Westland estate and the Ballysillan area. Over the last 48 hours there have been a series of violent incidents involving the pro-Shoukri faction and those loyal to Jackie McDonald, the south Belfast 'brigadier' and de facto head of the UDA in Northern Ireland.
The latest feud started with reports from Maghaberry top security prison that someone had tried to poison the Shoukri brothers. Andre is on remand facing extortion charges while his brother is also being held, accused of UDA membership.
On the outside, there has been at least one murder attempt on one of the Shoukris' allies; an attempt by the Shoukri faction to march on the homes of UDA men loyal to the leadership in the Tyndale/Ballysillan area; a pipe bomb found on the Westland estate; and an exchange of menacing statements between the leadership and the rebels.
The Shoukri brothers were expelled over allegations of widespread criminality. They counter that all UDA brigades are involved in racketeering.
