A student opened fire at Debsirin Nonthaburi School in Bang Kruai on Friday morning, killing two teachers and injuring at least 15 others before dying of self-inflicted wounds. Authorities have cordoned the campus and asked the public not to livestream or go near the area. No change to costs, rules or trade follows for Thai SMEs; if you operate near the school, expect temporary road closures and avoid the area while police work.
