TOKYO -- (UPDATE 2) Around 30 people on a US-bound jet were injured Friday, 10 of them seriously, apparently due to air turbulence on the Manila-Tokyo leg of the flight, airport officials said.
Ambulances took the injured to hospitals after the Northwest Airlines Boeing 747-400 jet landed at Narita International Airport near Tokyo at 12:19 p.m. local time (0319 GMT), an airport official said.
"Ten people were seriously injured and another 20 people suffered minor injuries," said a Narita International Airport spokesman.
Among the most seriously injured were three Filipinos -- two men and a woman -- Jiji national news agency reported, quoting local police.
The flight had been set to continue on to Los Angeles after the stopover.
Northwest Airlines spokesman Masashi Takahashi said: "Air turbulence is believed to be the cause. The turbulence occurred 25 to 30 minutes before landing, when the seat belt light was on.
"During the flight, we received a message from the pilot saying two or three people were injured. But [the pilot] probably assessed that an emergency landing was not necessary," he told Agence France-Presse.
"It is possible that the people injured did not have their seatbelts on, otherwise all of the 422 passengers would have been injured as well."
