Six people are dead after a shooting at a mosque in Quebec City, according to Quebec Provincial Police. Eight people were injured. The attack, which took place at the city's Quebec Islamic Cultural Center, is being investigated as an act of terrorism by police.

n what was described as a coordinated attack, witnesses say at least two gunmen wearing black fired indiscriminately into the dozens of worshipers in the mosque.

One person has been arrested, the department said. A previous statement indicated that two arrests had been made. It's not clear what caused the discrepancy.
The Canadian province's premier, Philippe Couillard, called the shooting a terrorist act on Twitter.
