(CNN)Two men who opened fire outside a contest for Prophet Mohammad cartoons in a Dallas suburb were shot dead by police Sunday night, authorities said.
The men began shooting at a security officer as the “Muhammad Art Exhibit and Cartoon Contest” at the Culwell Event Center in North Garland was coming to an end, the city’s Facebook page said.
The security guard was shot in the leg and taken to a local hospital. His condition is unknown.
FBI and local officials were checking on the gunmen’s vehicle for explosives, a law enforcement official told CNN. The area around the center was blocked off.
