Kyrgyz Airlines' Tu-154 passenger jet carrying 52 passengers and nine crew en route to the southern city of Osh, then to Moscow hit the U.S. aircraft standing on the tarmac of the Manas airport that also houses a U.S. military air base, said airport spokeswoman Ainura Tentieva.
The U.S. base said in a brief statement that a KC-135 tanker plane caught fire at Manas, but its crew of three got out safely and nobody was injured. It gave no other details.
Kyrgyz authorities closed the airport for several hours, and an official investigation was under way.
The U.S. military has maintained the Manas air base since 2001 to back operations in nearby Afghanistan.
