Terrorism charges have been laid against the man accused in the death of four people in London, Ontario.

The charges were unveiled in court Monday.

The 20-year-old suspect was already facing four counts of first-degree murder and one count of attempted murder.

Police say the suspect intentionally drove his truck into the family out for a Sunday evening walk because of their Muslim faith.

Three generations of the family did not survive and a 9-year-old boy was left an orphan.
