Three children avoided death when a cheering gunman fired a volley of shots at the home lived in by the family of a murdered pizza delivery driver.
Several rounds from what is believed to be a .22 pistol were yesterday shot at the house where relatives of Daniel Murray live, in the Norglen Parade area of west Belfast.
Two adults were also in the house at the time of the 1.30am attack, but all occupants escaped unhurt.
Local sources confirmed the home was lived in by relatives of Mr Murray (54), who was gunned down on May 9 last year in the Divis area of Belfast after he was lured into an ambush by a bogus fast food order.
One source said: "It's horrific that just over a year since Dan's death that his house is being shot at, especially with young children inside.
"It's sickening to think young kids could have died in this shooting.
"We could be looking a real tragedy today."
Another source added the gunman fired the shots from behind a wall outside the property and was heard "cheering and shouting" after the attack, before he fled in a waiting getaway car that beeped its horn several times as it sped away from the scene.
The Murray family were too distressed to speak after the gun attack.
It has not been confirmed which relatives of Mr Murray were inside the Norglen Parade home at the time of yesterday's shooting.
A PSNI spokesman said: "Thankfully no-one was injured as a result of this incident."
The shooting comes days after police seized four firearms and ammunition in the Norglen area on Saturday.
Mr Murray was targeted last May while sitting in his dark-coloured Ford Focus car in Lady Street after apparently being lured to the area by a fake takeaway order.
Two men were arrested over the murder, but both were later released unconditionally.
Mr Murray was previously targeted in a gun attack around a year before his death.
He was shot in the face near his home by dissident republican vigilantes in 2015 claiming to be members of paramilitary group Action Against Drugs.
Mr Murray, from the Turf Lodge area of west Belfast, said at the time he had been accused of being a drug dealer - which he denied - and would have to flee his home.
As he recovered from that shooting, he said the attack was an attempt to execute him.
He had also been wounded in a Continuity IRA gun attack before last year's murder attempt.
Mr Murray claimed that was an extortion bid, and again denied he sold drugs.
He challenged the paramilitaries to produce any evidence of criminal activity.
The same day Mr Murray was shot dead, two other men were targeted in paramilitary-style shootings including a 17-year-old.
Sinn Fein MP for West Belfast Paul Maskey said the attack on a house with small children inside was a "disgrace".
He added: "I condemn this shooting and it increases the urgency for all guns to be brought off the streets.
"No-one in this area or beyond wants to see houses shot at and these attacks have no place in today's society."
