Canadian police say a machete attack that killed one woman and injured two more in February was an act of incel terrorism.
Police arrested and charged a 17-year-old boy with first degree and attempted murder following the attack in a downtown Toronto massage parlour.
They have now upgraded those charges to "murder - terrorist activity" after discovering new evidence.

"[We] determined that this crime was in fact one in which the accused was inspired by the ideologically motivated violent extremist movement commonly known as incel - involuntary celibate," a Royal Canadian Mounted Police statement said.
"The public can be assured this appears to be an isolated incident and there is no further known threat to the public associated to the accused at this time."
The suspect appeared in court via video link on Tuesday to answer to the new charges following the incident.
A 24-year-old mother, Ashley Noelle Arzaga, was killed in the attack, while the female parlour owner and another man both suffered multiple stab wounds.
The incel movement is made up of self-described "involuntary celibate" heterosexual men who say they are unable to find sexual partners.
Grown through online forums like 4chan, the incel movement in rife with misogynistic discourse around women, often referred to as 'Stacys', who are said to reject incel men in favour of more attractive men.
The Toronto attack is not the first linked with the movement.
A 2018 van attack in the same city that killed 10 people was found to be motivated by the incel movement, as were a 2015 Oregon college shooting and a 2014 California shooting that killed nine and six people respectively.
