concourses at Miami International Airport, in the southeastern U.S. state of Florida, were briefly evacuated on Tuesday afternoon after a suspicious package was found in an area between the two concourses, but authorities later determined there was no danger from the package, news reports said.

Initial reports indicated the package, found at a checkpoint between concourses C and D at about 4:40 p.m. local time (0840 GMT), might have a possible explosive device, and passengers and employees at the two concourses were evacuated.

A bomb squad was called in to investigate the device, and Miami-Dade Police later determined the device was a battery charge, CBS News reported.

Air traffic was diverted away from the airport after the discovery, but passengers were allowed to return to the concourses about 40 minutes later and planes were allowed to land.
