A four-alarm fire overtook a Catholic church in Brooklyn on Easter Sunday, the FDNY said.

The fire – which occurred at Our Lady of the Rosemary of Pompei at 225 Seigel St., in East Williamsburg – began around 1:48 p.m., according to the NYPD. A firefighter and civilian both received minor, non-life threatening injuries, and were both being evaluated by emergency medical services, FDNY officials said.

Fire responders were still battling the blaze at the scene on Sunday afternoon. The cause of the fire also remained under investigation, officials said.

The building has also been evacuated. And the city’s emergency management system warned people near Siegel Street and McKibbin Court to avoid smoke and close their windows.

Those with heart and lung conditions were being instructed to seek medical attention if they start to experience chest pains or shortness of breath.

The church did not immediately respond to requests for comment.
