Canadian authorities on Monday charged a 27-year-old university student known for his far-right sympathies with six counts of first-degree murder in a mass shooting the day before at a local mosque.

Alexandre Bissonnette, described by neighbors and acquaintances as a socially awkward introvert who had recently adopted virulent political views, was also charged late Monday afternoon with five counts of attempted murder with a restricted firearm. The five surviving victims were still in the hospital, with two of them in critical condition, although hospital officials said their injuries were not life-threatening.

Handcuffed, his feet manacled and wearing a white prison jumpsuit, Bissonnette reportedly looked at the floor throughout the court hearing, aside from casting a brief glance at his lawyer. The prosecutor, Thomas Jacques, indicated that terrorist charges could be added later to the murder and attempted murder charges.
