At least four people have reportedly been killed in a shooting at a mosque in Quebec City, Canada.
Shots were fired at the Quebec Islamic Cultural Centre on Sunday night, police said.
Police said two people had been arrested, but did not provide a number for those killed or injured.
A witness told Reuters news agency that up to three gunmen had been involved. The news agency also reported a "heavily armed tactical squad" had been seen entering the mosque.
Local newspaper Le Soleil said it had obtained information that one of the suspects was a 27-year-old with "a Quebec name", and one had an AK-47 automatic weapon in his possession. Police, however, have not released such details.
The shooting happened at the mosque on chemin Sainte-Foy, one of two operated by the Islamic centre, during evening prayers.
