Phillippines ? Thousands of people lined up outside a stadium near Manila to watch a TV game show surged toward the gates Saturday in the mistaken belief they were open, and at least 74 people were trampled to death, officials said. About 500 people were injured.

About 30,000 people were waiting to get inside the Philsports Arena for the show “Wowowee” when the stampede occurred, said Vicente Eusebio, the mayor of suburban Pasig, where the stampede occurred.

President Gloria Macapagal Arroyo, who visited the injured in hospitals, ordered authorities to conduct a thorough investigation and submit a report to her in 72 hours.

Health Secretary Francisco Duque III said 74 people were killed, including a person who died of massive bleeding more than 12 hours after the stampede; 514 were injured.

Survivors said the game show was to include a raffle with a jackpot equivalent to $384.
