Somewhere on an older hard-disk I have a copy of all the terrorist incidents starting from the 1960s up to 2006 or so (web-scrapped at the time when that data was still partially open), no-where in there had I seen this type of events, there were mostly bombings, airplane kidnapping and the like. What you are describing falls though under the "insurrection" label, heck, we were saying the same thing about Ceausescu in December 1989 and thankfully no-one branded us as terrorists (I'm from Romania).
