A fire that broke out early Monday at the Fort Pierce, Fla., mosque where Orlando massacre shooter Omar Mateen worshiped is considered arson, according to investigators. A 911 call about 12:30 a.m. alerted authorities that flames were coming out of Islamic Center of Fort Pierce, authorities said. Mateen, who lived in Fort Pierce, killed 49 people at Orlando's Pulse nightclub in June and was known to worship at the mosque. Leaders at the Islamic Center have said that since the nightclub shooting the facility has received threats and that security had been stepped up. "This is a terrible tragedy, not only for the Islamic Center, but for our community,” he said.
