An attacker opened fire in a gay nightclub late Saturday, killing five people and wounding 18, officials said. The club said the gunman was subdued by patrons.
Authorities received a report of a shooting at Club Q at 11:57 p.m. and responded within minutes, said Lt. Pamela Castro of the Colorado Springs Police Department.
The violence is the sixth mass killing this month and comes in a year when the nation was shaken by the deaths of 21 in a school shooting in Uvalde, Texas.
Castro had few details beyond the number of dead and wounded. She said the suspect was injured but didn't know how and that the FBI was on the scene and assisting.
The police department planned a news conference for 8 a.m. (10 a.m. EST) on the investigation.
The latest incident occurred as anti-gay rhetoric has intensified by extremists. In a statement, Club Q termed the shooting a hate attack.
"Club Q is devastated by the senseless attack on our community," the club posted on its Facebook page. It said its prayers were with victims and families, adding: "We thank the quick reactions of heroic customers that subdued the gunman and ended this hate attack."
Club Q is a gay and lesbian nightclub that features a "Drag Diva Drag Show" on Saturdays, according to its website.
In addition to the drag show, Club Q's Facebook page said planned entertainment included a "punk and alternative show" preceding a birthday dance party, with a Sunday "all ages brunch."
Colorado Springs is a city of about 480,000 located about 70 miles south of Denver that is home to the U.S. Air Force Academy, as well as Focus on the Family, a prominent evangelical Christian ministry.
In November 2015, three people were killed and eight wounded at a Planned Parenthood clinic in the city when authorities say a man opened fire because he wanted to wage "war" on the clinic because it performed abortions.
The motive behind Saturday's shooting was not immediately known but it brought back memories of the 2016 massacre at the Pulse nightclub in Orlando, Florida, that killed 49 people. And it occurred in a state that has experienced several notorious mass killings, including at Columbine High School in 1999, a movie theater in suburban Denver in 2012 and at a Boulder supermarket last year.
In June, 31 members of the neo-Nazi group Patriot Front were arrested in Coeur d'Alene, Idaho, and charged with conspiracy to riot at a Pride event. Experts warned that extremist groups could see anti-gay rhetoric as a call to action.
The previous month, a fundamentalist Idaho pastor told his small Boise congregation that gay, lesbian and transgender people should be executed by the government, which lined up with similar sermons from a Texas fundamentalist pastor.
There have been 523 mass killings since 2006 resulting in 2,727 deaths as of Nov. 19, according to The Associated Press/USA Today database on mass killings in the U.S.
