Online death threats made to critic of Bloody Sunday report
A poster of DUP MP Gregory Campbell with a bullet hole through his head has been taken off Facebook.
The online death threats came after the Democratic Unionist criticised aspects of the Saville Report on Bloody Sunday.
Mr Campbell called for more focus on IRA victims after the £200m investigation into the deaths of civil rights protesters at the hands of soldiers found the demonstrators innocent.
Mr Campbell said: "The type of bigoted fascist nonsense expressed on these sites is similar to the beliefs that led to 3,500 deaths in Northern Ireland.
"Some of the border areas and the west bank of Londonderry saw unionists move out in their thousands because of republican paramilitary action based on beliefs such as these."
He called for greater scrutiny and action by social networking sites such as Facebook after being alerted by a member of the public to the numerous attacks.
"I was informed by a member of the public that a group site had been set up, upon investigation I discovered that there were scores of vile, vicious references to me and some of my colleagues, a small number threatened to have me attacked if I appeared anywhere on the cityside of Londonderry, others were more precise in their threats," he added.
He said a similar Facebook site was also set up which contained a picture of an altered election poster with a bullet-hole through his forehead.
Meanwhile, paratroopers from the battalion involved in Bloody Sunday claimed in an open letter that the Saville inquiry was "fundamentally flawed", according to a national newspaper.
The letter also attacked Northern Ireland's Deputy First Minister Martin McGuinness, saying: "A more untruthful and unreliable witness would be hard to find."
