Following the release of a report that ISIS may be planning a terrorist attack Sunday in Atlanta at Philips Arena during WWE's Survivor Series event, the FBI reportedly acknowledged the threat Saturday.

According to Mark Winne of WSB-TV, an FBI source informed him that the threat is being taken seriously.

Despite that, a source told Winne there is no active plot regarding an attack at Survivor Series. The FBI subsequently released a statement to WSB-TV as well:

The FBI is aware of reports of an alleged threat that includes an Atlanta, Georgia venue and event. While we take all threats seriously, we do not have specific or credible information of an attack at this time. We have, however, made the proper notifications as we continue to work closely with our law enforcement and private sector partners to keep our community safe.

On Sunday, WWE released a statement, saying no bags would be allowed in the arena and encouraging fans to use public transportation to the event.

News of the potential threat first came to light Saturday in a post by OpParisIntel—which is part of the hacker group Anonymous—on PasteBin.com (h/t IBTimes.com).

Per the post, intelligence suggests ISIS may be planning further attacks in Paris as well as attacks in Italy, Lebanon and Indonesia Sunday.

According to CNN.com, at least 128 people were killed and many more were injured in a terrorist attack in Paris last week.

"His agency is working closely with the FBI, the Georgia information sharing and analysis center and others in evaluating the threat on a Sunday WWE event in Atlanta reported by the group Anonymous," Winne said.

Details surrounding the threat are scarce, but WWE will proceed with Survivor Series.
