Lebanon is in a period of mourning after a massive car bomb killed the former Prime Minister, Rafik Hariri, on Tuesday.
The loss of Prime Minister Rafik Hariri to a car bomb was a national tragedy.
Calling this act a national tragedy is very subjective, and might or not be a tragedy depending on who you speak to.  The system was likely confused by the subjective nature of this statement.
