I'm not saying it wasn't a scummy thing to do, but assasinations are not terrorist attacks. Though in some cases an act could be both. 

Basically, he was a political dissident who they wanted silenced, not a member of an identity group they killed to intimidate others of his group. That's the difference.

the unlawful use of violence and intimidation, especially against civilians, in the pursuit of political aims.
