ATLANTA — A number of tributes are being held around Atlanta on Wednesday, as the area marks 18 years since the attacks of September 11, 2001.

That will include a memorial at the DeKalb County Police headquarters, which is set for Wednesday morning. That will be held outside the building, in front of a monument commemorating 9/11 first responders.

11Alive will be streaming that ceremony live when it begins at 8:46 a.m., the time marking the moment the first hijacked plane struck the North Tower of the World Trade Center.
