President Obama again avoided attributing the Orlando mass shooting to radical Islamic terrorism Monday, saying instead that it appeared to be motivated by “extremist information distributed over the Internet.”

He also talked about the Islamic State’s “perversion of Islam” on the Internet and once again partly blamed the availability of guns in the U.S. for the attack that killed 50 people, including the killer. Fifty-three others were injured, five of whom are in grave condition, according to the Associated Press.
