Debsirin Nonthaburi School resumed on-site classes after the 7 August shooting that killed nine people. The Department of Mental Health has set up a support centre for the first week, with about 80 staff and psychologists, and plans support for up to a year. About 60 students are rated high risk and are being monitored. For a Thai business owner there is little direct action here; it is a human-interest story about a tragedy, with the main practical signal being that schools and parents may need counselling resources. No change to costs, rules or planning is implied.
