Hivetyrant-It was an armored vehicle without a gun.
Besides even if it did have a gun (which i seriously doubt) it still does not qualify for a tank-it is, as felix pointed out, too light. And yet another thing-Tank's basic design is not made for carrying additional personnel around. APC, like one on the picture, is made specifically for that purpose.
In short we can conclude from this story that news agencies (apart from Israeli, which called it APC from the start) do not know some very basic military stuff.
Woe and shame to them!
