Speaking of propaganda. One of the images of dead children being used was on his page back in December referencing Syria and on a Hamas twitter page at the same time referencing a 'toxic rocket attack' in December.
Translated:
Massacre of 100 martyrs, mostly women and children, adding to the approximately 400 State suffered from #الروسية toxic missile air strikes
At that, there are a lot of posts, tweets, and repeated images saying there have been 'toxic missile strikes'.
Either there are a lot of chemical attacks going on that we aren't hearing about or they have been trying to spread stories of it for a while.
