Passengers were ordered out of public areas of the domestic terminal at Hartsfield-Jackson International Airport, the United States’ busiest by passenger volume, but the site was quickly cleared and operations resumed, airport officials said.
Parts of Denver airport were also evacuated on Tuesday, hours after at least 31 people were killed and 271 wounded in attacks on Brussels airport and a rush-hour metro train, as airports across the United States tightened security.
US officials were trying to find Americans missing after the attacks, which the officials said injured about a dozen US citizens including three Mormon missionaries, a US Air Force airman, and four members of his family.
