Two gunmen were shot dead after they opened fire outside a conference on cartoons of Prophet Muhammad in Texas state, authorities said.
The incident took place at the Culwell Event Center in Garland city on Sunday evening.
Garland's city government issued a statement that the Muhammad Art Exhibit event was coming to a close when "two males drove up to the front of the building in a car and started shooting at a security officer," USA Today reported.
"Garland police officers engaged the gunmen, who were both shot and killed," the statement said.
The security officer, a Garland Independent School District employee, was identified as Bruce Joiner. He was shot in the lower leg and suffered non-life-threatening injuries, according to a spokesman for Garland police.
Authorities cannot confirm immediately if the shooting was directly related to the conference, which was organised by the New York-based American Freedom Defence Initiative.
Around 200 people attended the event, most of them from out of Texas.
