The five suspected ISIS operatives, who were arrested in a joint operation spread across different states, were planning to target some right-wing leaders, an investigation into their chats revealed.

The US State Department on Thursday threatened to strip visas over online support for the killing of right-wing influencer Charlie Kirk, encouraging internet users to flag foreigners’ posts.

Charlie Kirk, prominent conservative figure and Turning Point USA co-founder, was fatally shot while discussing gun violence at Utah Valley University. The FBI is seeking a suspect, offering a $100,000 reward, and has released images of a person of interest. Political figures across the spectrum have condemned the attack, with tributes pouring in for Kirk.
