The US federal authorities are in search of two Afghanistan men, who went missing from the Moody Air Force Base in Georgia.
The men, who are undergoing military training at the base in Valdosta, failed to turn up at their regular maintenance practice.
They are assigned to the 81st Fighter Squadron, which undertakes training for Afghan airmen, the Atlanta Journal-Constitution reported.
This is the second time that Afghanistan men have gone missing from a US base in the recent years. A soldier in the Afghanistan army went missing during a training exercise at a military base in Massachusetts last year.
He was granted asylum by the US in January, reported Reuters.
The men missing from Georgia have been at the base since February and were screened before arriving in the US about a year ago.
While the reason for their disappearance is not yet known, they do not pose any apparent security threat to the country, an air force spokesman said.
