Canadian police are hunting for two men who set off a homemade bomb in an Indian restaurant in Mississauga, injuring 15 people on Thursday evening.

Footage released by police shows the two suspects entering the city's Bombay Bhel restaurant with an object resembling a paint can moments before the bomb went off.

The pair fled the scene late on Thursday and a manhunt is under way. The motive for the attack is unknown and there was no immediate claim of responsibility.
