Orlando mayor Buddy Dyer has said he is uplifted by the way the community has come together during a city-wide prayer service for the 49 people who were killed in a nightclub shooting.
More than 1,000 people - including many clergy and local, state and national civic leaders - met at First Baptist Orlando to hold a vigil for the victims of the Sunday morning shooting at the Pulse nightclub.
Mr Dyer said to the crowd: "We will not be defined by the act of a hate-filled killer. We will be defined by our love, compassion and our unity."
He said officials are putting together an Orlando Family Assistance Centre. It will open on Wednesday at Camping World Stadium.
The shooting at the gay dance club ended when police killed gunman Omar Mateen.
Meanwhile, his ex-wife has urged people not to quickly assign a motive to the attack.
Sitora Yusufiy said in an interview on CNN that Mateen was unstable and prone to emotional outbursts while they were together but she never heard him express any radicalism.
She said she had not talked to him for a while but would not be surprised to learn he was leading a double life and in deep internal conflict.
"I just hope that people, without making rash judgments on one another, can truly understand that this is one insane person that did such a tragic thing," she said.
