Travel warning is a phrase that public know very well. Here is a name to the area that make a country worried about their citizens coming there.
There is a fatal accident happening to the strangers in that place or accident attacing to the area where strangers gather together. And a country as indentity of stranger’s place plotting all places around them is dangerious. As a good citizen he or she is better no come there.
As far as I know, public horriable is being taken by “a strange actor” who has no careousity. The most important thing for him or hers, he or she is feeling happy to see everything happend to the public area.
He or she is not a hero. But a worry is part of his or her doing as a first target.
