MANILA — Officials say 17 flights have been diverted from Manila's international airport due to an air traffic equipment glitch.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.” The flights were diverted to airports at the former US-run Clark Air Base north of Manila, and in central Cebu and Iloilo cities. — AP
