The names and passport photos of two missing Afghan national air force students were released Thursday. But there's still no sign of the two men, last seen Friday on Moody Air Force Base.

The men have been identified as Mirwais Kohistani and Shirzad Rohullah, Channel 2 Action News reported. The two are among a group of 23 from Afghanistan who have been at the base since February and both are assigned to the 81st Fighter Squadron.

But a federal investigation was launched when Kohistani and Rohullah but did not show up for work Monday, Moody said in an emailed statement.

“The students have trained alongside American counterparts for the entirety of 2015 and do not pose any apparent threat,” Moody said Tuesday. “There is a well-coordinated process among federal agencies to locate the individuals as quickly as possible and return them accordingly to the proper authorities to manage their present situation.”

On Thursday, Moody said the Department of Homeland Security and Department of State were leading the investigation to find the two men.

"Based on the current information we have, we still don't believe that these individuals pose any apparent threat," Moody posted on its Facebook page Thursday evening.

The 81st Fighter Squadron was re-activated in January and charged with training Afghan airmen, who arrived the following month. The squadron will grow to 20 A-29 Super Tucano aircraft that will be used to train 30 Afghan pilots and 90 maintainers at Moody through 2018, the Air Force previously said.
