Not backing Insaani up but it is mentioned in the article that he is a Christian. However, as Rojava said, his reasons for the attack might as well not related at all with Christianity and more related to the usual White Supremacy thing, considering an article I read before suggested the clothing that he wore has swastikas on it.
The pickup driver was wearing what appeared to be a bullet-proof vest, a military-style helmet and clothing that possibly had swastikas on it, Mr Savehilaghi said the traumatised driver had told him.

Though it's best if we wait for the official inquiry on his motive(s).
