Original story

An explosion Thursday at an Indian restaurant in Ontario, Canada, has injured at least 15 people, police said.

Reports stated police and paramedics were called to Bombay Bhel restaurant on Hurontario Street & Eglinton Avenue, Mississauga, around 10.30 p.m. EDT. The front windows of the restaurant were blown off. The reason for the explosion has not been determined yet.

Some news reports suggested an incendiary device exploded at the Mississauga restaurant; however, there has been no official confirmation.

At least 15 people were taken to nearby hospitals. Three of them, with critical injuries, were transported to Toronto trauma center.

Peel Regional Police said the bomb squad is on the scene, trying to determine if explosives are involved and added the shopping plaza where the restaurant was located and the surrounding area were cordoned off.

A spokesperson for the police department said the building was intact but there was a lot of broken glass everywhere.

This is a developing story.
