A shooting has occurred during the first week of classes at a Minneapolis Catholic school, the Minnesota governor and authorities say. 

There was no immediate information on any injuries.

Governor Tim Waltz said on social media that he had been briefed on a shooting at Annunciation Catholic School.

"I'm praying for our kids and teachers whose first week of school was marred by this horrific act of violence," Waltz wrote on X.

A person answering the phone at Annunciation School said students were leaving the site.

The pre-kindergarten through eighth grade school had an all-school Mass scheduled at 8.15am on Wednesday, according to its website. 

Monday was the first day of school.
