Police said passengers were evacuated from a terminal at Atlanta's airport after a bomb squad investigated a suspicious package, but airport officials said operations have returned to normal.
Atlanta police Officer DT Hannah said the package was "cleared" and the terminal was reopened this morning.
Airport officials said bomb-sniffing dogs had indicated "a positive hit" while checking an unattended bag in the South domestic terminal around 9:41 AM local time today. They said passengers were allowed to re-enter the terminal less than 30 minutes later.
The evacuation comes one day after attacks at an airport and subway system in Brussels, Belgium, killed at least 34 people, including three suicide bombers, and injured 270 others.
Hartsfield-Jackson Atlanta International Airport is the world's busiest airport, with 101.5 million passengers in 2015.
