A student opened fire at a high school in Nonthaburi province outside Bangkok, killing at least five people at the school and wounding several others, authorities said. Officials also said the gunman appeared to have killed his two grandparents separately, taking the overall death toll to at least seven. The shooter later died by suicide. Police responded to the school on August 7 as distressed students and families gathered outside, while investigators worked to establish the sequence and motive of the attacks.
