The father of three children found dead in their home has said he was "paralysed with grief" when told of the tragedy.
Eight-year-old twins Austin and Luke Riggi and their five-year-old sister Cecilia were found in an Edinburgh townhouse a week ago following reports of an explosion.
Their mother, Theresa Riggi, 46, who is being treated in hospital after apparently falling from a second-floor balcony, has been charged with their murder.
Engineer Pasquale Riggi, 46, spoke of his last outing with his "happy, healthy, bright" children and how he was to celebrate what would have been Cecilia's sixth birthday on Monday.
He said his memories of the children are providing comfort as he attempts to deal with the shock of losing his family.
Speaking from a hotel in Aberdeen, Mr Riggi said: "You are paralysed with grief. You are not sure what to do next.
"It is bad enough that you have lost three beautiful children, but certainly the tragedy around their deaths makes it much more painful.
"The reality of it all is difficult to take all at once. You can't even get your head around it.
"The difficult part, obviously, is seeing constant reminders on a daily basis in front of you - it's playing out in the newspapers and on TV.
"It's almost like it's happening to someone else and you keep asking yourself, 'is it me, is this my family?'. And then the reality hits you that it is."
