Canada 'terror' attacks suspect is 'Somali refugee known to police'

A car and knife attack on a police officer and a high-speed chase of a moving van that left four people injured was the work of a Somali refugee known to police for extremist ideology, Canadian authorities said.

Marlin Degrand, assistant commissioner of the Royal Canadian Mounted Police, said officers took a 30-year-old man into custody in the western Canadian city of Edmonton, Alberta.
