From USA TODAY.

Two children were killed Wednesday and at least 17 people were injured when a shooter fired through the windows of a Minneapolis Catholic Church toward young students worshipping at Mass, authorities said.

The shooting occurred at Annunciation Church, which also houses a school, just before 8:30 a.m., authorities said. The shooter approached the outside of the church building and fired inside toward the children sitting in pews, Minneapolis Police Chief Brian O’Hara said.

The two children killed were ages 8 and 10. Fourteen of the 17 injured were children, and two of them are in critical condition, O’Hara said.

The assailant died of a self-inflicted wound at the rear of the church, O’Hara said.
