The "Islamic State of Iraq and Syria" (ISIS) on Wednesday (July 25th) claimed responsibility for a weekend shooting that killed two people in Canada's Toronto, AFP reported.

The group's propaganda agency Amaq said the attacker "carried out the attack in response to calls to target nationals of countries of the coalition" fighting ISIS in Syria and Iraq since 2014.

Faisal Hussain, 29, killed an 18-year-old woman and a 10-year-old girl in the shooting rampage on a Toronto street on Sunday evening, Canadian police said.

He was found dead near the scene of the shooting after an exchange of gunfire with police.

The attack in Toronto's bustling Greektown neighbourhood at around 10 p.m. Sunday also wounded 13 people aged 10 to 59, officials said.

Hussain's family, in a statement to CBC News, denounced his "horrific actions" and said he was suffering from mental problems.

They said he had battled "severe mental health challenges, struggling with psychosis and depression his entire life".

They said medications and therapy had been unable to treat him.

ISIS has claimed a string of deadly attacks in the West in recent years. Canadian citizens have also been intercepted trying to reach Syria to join ISIS.
