If a European monarch was dumb enough to go into Ottoman territory to negotiate a peace/trade deal/whatever (instead of sending ambassadors) but was dumb enough to bring much of his family there, what would happen if they are all killed off by road bandits. Bandits or "bandits" you can chose, but the European powers have no evidence either way. Suppose this is during the Ottoman-French alliance, but obviously the French have nothing to do with this.
