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.

This incident has been linked to ISIS, so none of that is especially relevant in this context.

It's relevant to why people don't bat an eye when yet another thing explodes in Lebanon. Even if this time was different in the details.
