Two unidentified men have walked into a restaurant in the Canadian city of Mississauga and set off a bomb, wounding more than a dozen people, and then fleeing, authorities say.
The blast went off in the Bombay Bhel restaurant at about 10.30pm on Thursday.
Fifteen people were taken to hospital, three of them with critical injuries, the Peel Regional Paramedic Service said in a Tweet.
The two male suspects went into the restaurant and detonated their improvised explosive device, Peel Regional Police tweeted. The men then fled.
There was no immediate claim of responsibility.
Police posted a photograph on Twitter showing two people with dark zip-up hoodies walking into an establishment with one of them appearing to be carrying an object.
The attack in Mississauga, Canada's sixth largest city about 32km west of Toronto, comes a month after a driver ploughed a rental van into a lunch-hour crowd in Toronto, killing 10 people and injuring 15.
