Arrests of 8 with suspected ISIS ties in U.S. renew concern of terror attack

Washington — The arrests of eight Tajik nationals with alleged ties to ISIS have renewed concerns about the terrorist group or its affiliates potentially carrying out an attack in the U.S. 

The arrests in Los Angeles, New York and Philadelphia came as U.S. officials have been warning for months about the potential for a terror attack and as the U.S. has been on heightened alert. 

"I see blinking lights everywhere I turn," FBI Director Christopher Wray testified to the Senate Judiciary Committee in December, telling lawmakers, "I've never seen a time where all threats were so elevated all the time."
