The mother of the man identified as Ottawa gunman has told The Associated Press she is crying for the victims of the shooting, not her son.
In a brief and tear-filled telephone call Thursday, Susan Bibeau said she did not know what to say to those hurt in the attack.
"Can you ever explain something like this?" she said. "We are sorry."
Authorities have identified the shooter as Michael Zehaf-Bibeau, whose gun rampage in the Canadian capital was stopped cold when he was shot to death by Parliament's ceremonial sergeant-at-arms.
One victim was killed and two other people were wounded in the attack.
