How to compress images coming from third party websites and CDNs?

I am following GTMetrix report suggestions in which the report has pointed out some images that should be compreseed BUT the problem is that the images are coming from third part sites! Either they are from FBCDN or from another site. So how can I compress/optimize these images?

e.g https://scontent.xx.fbcdn.net/v/t51.12442-15/33687098_2072367586314613_6533476226013593600_n.jpg?_nc_cat=0&oh=d255f481843f4f945397fedd0ff489ab&oe=5BB74460

The above image is loading from Facebook CDN.

The above image is loading in our website AWS
