ATHENS — Forest fires are raging in Greece, but tempers are flaring too. In a televised emergency briefing this week Greece’s minister of civil protection, Vassilis Kikilias, said that “arsonist scum are setting fires that are threatening forests, property and, most of all, human lives,” adding that “You are committing a crime against the country, you will not get away with it, we will find you, you will be held accountable.”
