A major airport in the southern state of Alabama reopened Sunday after police swept the airport for bombs and declared an "all clear", dpa reported.
The Birmingham-Shuttlesworth International Airport tweeted that "the airport has been secured and operations are resuming."
Sergeant Johnny Williams, Junior, police spokesman, said that bomb sniffing dogs had determined there was no threat, according to The Birmingham News newspaper. The threat was reported to have been made in the form of a written note. The FBI's bomb technicians and joint terrorism task force worked with local police after the threat was received.
At least eight flights were diverted from landing during a three-hour period after the evacuation, according to the airport's website.
The evacuation came just two days after a gunman spread terror through the Los Angeles International Airport by killing a government security officer and wounding seven other people. The gunman was in police custody and was charged Saturday with murder.
