The NYPD has stepped up its presence at mosques around the city in response to the deadly shooting at a mosque in Quebec City on Sunday night.
Officers and patrol cars were seen guarding several mosques Monday morning.
Police say they are monitoring the situation in Canada, and Mayor Bill de Blasio has promised to protect Muslim New Yorkers.
Six people were killed when gunfire erupted during evening prayers at the Quebec City Islamic Cultural Center. Eight others were hurt.
Two people are under arrest, according to authorities.
Canadian Prime Minister Justin Trudeau called the shooting an act of terrorism, and said his government would protect the rights of Muslim Canadians.
