Nashville explosion: Authorities say no indication others involved, say they haven’t tied blast to case of domestic terrorism

FBI Special Agent in Charge Doug Korneski said that they are still following leads but there is no indication that any other persons were involved in the blast which rocked Nashville, Tennessee on Friday. Asked what would be needed to classify the blast as a case of domestic terrorism, Korneski said an event needs to be connected to an ideology, saying it's a "use of force or violence in the furtherance of a political social ideology" and they have not tied the Nashville explosion to such an ideology.
