Two unidentified men walked into a restaurant on Thursday in the Canadian city of Mississauga and set off a bomb, wounding 15 people, local police said. The blast went off in the Bombay Bhel restaurant at about 10:30 p.m local time. Fifteen people were taken to hospital, three of them with critical injuries, the Peel Regional Paramedic Service said in a Tweet. It said "two suspects attended the scene," detonated the devices and fled. The plaza where the restaurant is located was still sealed off on Friday. Andre Larrivee, who lives in a nearby condo, said he was watching television and heard a loud explosion. "It was really loud," he said, comparing the noise to an electric generator that had exploded at a nearby construction site recently. Peel region polices tweet described the first suspect as in his mid-20s, 5-foot-10 to 6-feet with a stocky build, wearing dark blue jeans, a dark zip-up hoodie and a baseball cap with a light grey peak. The second suspect is described as a little shorter with a thin build, wearing faded blue jeans, a dark zip-up hoodie pulled over his head, grey t-shirt and dark colored skate shoes. Police posted a photograph on Twitter showing the two people. The attack in Mississauga comes a month after a driver plowed his white Ryder rental van into a lunch-hour crowd in Toronto, killing 10 people and injuring 15.
