In the bottom right image, the top right do appear to be AKs with the stock removed. The top center could be as well but it's hard to tell with that angle and they might be RPKs as well.
At least correctly differentiating between western and combloc weaponry is pretty impressive for two finance reporters.

Well don’t go Joker on us yet. They appear to be AKMSs with one being perhaps a Chinese type 56-1.
