Martin McGuinness has launched more stinging criticism at dissident republicans, after it emerged a letter bomb was sent to Secretary of State Theresa Villiers at Stormont Castle.
In a tweet on Tuesday the deputy First Minister called those behind the latest letter bomb “bitter and twisted little minds”.
His tweet also seemed to refer to recent vandalism at churches, as well as graves at Carnmoney Cemetery including one belonging to Shankill Butcher Lenny Murphy.
He tweeted: “Letter bombs, attacks on places of worship, graves & orange halls are the offerings of bitter & twisted little minds & will further nothing.”
Tuesday’s letter bomb is the fourth to have been sent in the past five days, with two others posted to PSNI Chief Constable Matt Bagoott and Chief Inspector John Burrows, the police commander in Londonderry and one to the Public Prosecution Service.
In 2009 after the murders of two British soldiers at Massereene Army Barracks in Antrim Mr McGuinness called dissidents “traitors to the island of Ireland”.
