Twitter Inc. and law enforcement authorities are investigating alleged threats made by Islamic State militants against the social media network's co-founder and other employees, the company said in reaction to media reports.
Islamic State supporters, in online posts on Sunday, called for attacks against Twitter and its "interests," including death threats, according to the online news media company Buzzfeed as well as the NBC news network.
"Our security team is investigating the veracity of these threats with relevant law enforcement officials," a representative for Twitter said in a statement on Monday. Buzzfeed first reported the story on Sunday.
