Planes diverted Tuesday from Manila include five international flights of Asiana Airlines, Thai Airways, China Southern Airlines, Philippine Airlines and Zest Airway from South Korea, Thailand and China.
A Manila International Airport Authority advisory says the planes were diverted "due to air traffic facility problem." It did not elaborate and officials authorized to explain could not immediately be reached for comment.
The flights were diverted to airports at the former U.S.-run Clark Air Base north of Manila, and in central Cebu and Iloilo cities.
Jen Franco of the airport's public affairs office says the glitch was repaired shortly after noon. All 17 diverted flights later flew to Manila airport.
