Vigils planned in Indiana following deadly Florida shooting

INDIANAPOLIS (AP) - Gay rights activists in Indiana are planning evening vigils following a shooting at a gay nightclub in Florida that left more than 50 people dead.

Vigils will be held Sunday evening in Indianapolis and at The LGBTQ Center in South Bend.

Gov. Mike Pence has directed flags be flown at half-staff at state facilities to honor victims. He calls the killings a "senseless act of terror."

Indianapolis Mayor Joe Hogsett has also called for flags in Marion County be flown at half-staff.

An armed gunman opened fire inside a crowded gay nightclub in Orlando early Sunday before dying in a gunfight with SWAT officers.

The attack killed at least 50 people, making it the deadliest mass shooting in American history. Authorities were investigating it as an act of terrorism.
