Welcome to the News Hour. Another mass shooting, this time during Mass at a Catholic school in Minneapolis,

has left at least two young children dead and another 17 people injured, most of them children.

Authorities say they don't yet know of a motive, but said the shooter released a manifesto in social media that has since been taken down.

In South Minneapolis this morning, excitement for the first week of school turned to terror.

As an attacker, armed with a rifle, shotgun and pistol, opened fire into the windows of the church

at Annunciation Catholic school. As the morning went on, ambulances lined the street, and parents and loved ones, clearly overwhelmed

with fear, rushed to the family reunification zone near the school.

My husband's a firefighter, and he got a phone call this morning and said that there

was a incident at Annunciation and that's where my niece and nephew go to school. We live nearby

so he just took off on foot and my brother-in-law is a firefighter too, but it just did so awful and

it's so scary. And I just am really proud of my husband and my brother-in-law for just running into

the danger. And I just pray for the community.

The grandfather of a 10-year-old student at Annunciation told the news hour that his grandson

was in shock, having seen a friend covered in blood.

The sheer cruelty and cowardice of firing into a church full of children is absolutely incomprehensible.

Minneapolis Police Chief Brian O'Hara called this a deliberate act of violence against innocent children.

At this point, we know we have a total of 19 victims from this tragedy.

Two were young children ages 8 and 10 that were sitting in the pews at mass when they were shot and killed.

They were pronounced deceased on the scene.

There were another 14 children between the ages of 6 and 15 that were injured by gunfire.

There were also three adults in their 80s that were parishioners here, attending mass, that were also shot in this incident.
