I haven't looked into this specific incident but historically an example is Hezbollah who participates in the Lebanese government and is known to have supported any number of similar incidents in the past. They are a national level political party in Lebanon, and while radical by American standards I'm skeptical they are viewed as "fringe" in Lebanon. https://en.wikipedia.org/wiki/History_of_Lebanon#Cedar_Revolution_and_2006_War_.282005.E2.80.93present.29 https://en.wikipedia.org/wiki/History_of_Lebanon#Cedar_Revol...
