Excerpt:
Two gunmen were killed after they opened fire Sunday evening outside an event hosted by an anti-Islam group in Garland, Tex., featuring cartoons of the Prophet Muhammad, local officials said. According to the authorities, the two assailants shot a security guard and were, in turn, shot and killed by police officers.
Officials did not name the gunmen or assign a motive for the attack. A spokeswoman for the F.B.I. in Dallas said the agency was providing investigative and bomb technician assistance to the Garland police.
The City of Garland confirmed the episode in a Facebook posting.
