BANGKOK: A large collapsed part of the roof at a Bangkok movie theater complex on Thursday but caused no serious injuries.

The fire in the Major Cineplex Pinklao reportedly began in a third-floor cinema in the seven-story shopping and theater complex. About 30 to 40 fire trucks and 100 crew members battled the blaze, which sent large plumes of black and white smoke into the sky.

Members of Bangkok's Emergency Medical Services said a firefighter and another man were treated for slight injuries.

The building is in Thonburi, across the Chao Phraya River from Bangkok proper. It is owned by Thailand's largest operator of movie theaters, the Major Cineplex Group.
