Multiple bomb threats forced at least six area courthouses to evacuate Thursday afternoon, and officials don't yet know if the threats were coordinated.

At roughly 3:20 p.m., a man called officials in Clark County and said there were several explosive devices inside the courthouse in Vancouver. The man said the bombs would go off in 20 minutes.
