The shooting of a man in Portadown, Co Armagh, early yesterday has been linked to an ongoing loyalist feud between the LVF and UVF in mid-Ulster.
The attack took place around 8 a.m. as workmen arrived at a building site just off Princess Way in the loyalist Killycomaine estate.
As one of the workmen, an 18year-old, went to open a store on the site, he was approached by two masked gunmen who had been waiting nearby. The teenager ran off but was chased by the gunmen, who fired at least four shots at him.
The victim was hit in the arm but managed to flee to a nearby house. He was later taken to Craigavon Area Hospital, where last night his condition was described as stable.
Three weeks ago, the teenager's home was damaged in an incident which has also been linked to the LVF/UVF feud. His father, who works at the same building site, was not injured in yesterday's attack.
In Belfast, a man whose home was one of three attacked overnight has denied he is a member of the Loyalist Volunteer Force. No one was injured in the attacks in the loyalist Ballysillan area in the north of the city.
The first attack happened at about 9 p.m. on Wednesday, when a number of men smashed their way into a house at Ballysillan Avenue.
The resident, who did not want to be identified, told the BBC he was a supporter of the Orange Order's stand at Drumcree and said: "The UVF think I'm in the LVF but I am not."
Mr Billy Hutchinson of the Progressive Unionist Party, which has links to the UVF, said he believed the attacks arose as the result of a quarrel over a mural which was to be painted on a nearby leisure centre.
Shortly after 1 a.m. yesterday, windows were smashed at a house in the same street and a car parked at the back of the house was found alight.
About the same time, a house at Benview Park was set alight. No one was inside.
