INDIANAPOLIS (AP) — Gov. Eric Holcomb has directed flags to be flown at half-staff across Indiana to honor the victims of the Texas church shooting.

Holcomb issued the order Monday, which lasts until sunset Thursday.

Twenty-six were killed and 20 others wounded when a gunman opened fire at First Baptist Church in Sutherland Springs, Texas, during Sunday services.

Law enforcement officials say the gunman was 26-year-old Devin Kelley, who died later from what's believed to be a self-inflicted gunshot wound.

Holcomb's directive comes after President Donald Trump issued a similar order across the U.S.

The Republican governor called the mass shooting "senseless and horrific."
