(CNN) A 95-year-old World War II veteran says he was so saddened by the horrific mosque attacks in Christchurch, New Zealand, that he took four buses to attend a solidarity march against racism in Auckland.

John Sato told Radio New Zealand he couldn't sleep the night after the March 15 terror attacks that left 50 people dead.

"I stayed awake quite a lot at the night. I didn't sleep too well ever since. I thought it was so sad. You can feel the suffering of other people," Sato said

So he decided to get to the rally Sunday any way he could from his home in the Auckland suburb of Howick.

Once there, he was supported on the arms of a police officer and another man. The scene was captured in a photo taken by Alexa Unrein, who was also attending the march.
