Former Prime Minister Rafik Hariri, also a prominent anti-Syria political figure, was killed in a suicide bombing in February last year, which led to rising anti-Syrian waves and the withdrawal of Syrian troops from Lebanon.
Hariri was a suicide bomber. 
I'm not sure why it was difficult.  Hariri was killed by a suicide bombing, he wasn't a suicide bomber, so my statement was incorrect.
