Use a curved spanner. You can push the two ends close enough together so that the sharp points both go into the holes, and then twist counterclockwise.
This is a great tool to have if you do any repairs later, particularly on lenses. So consider it an investment. :)
I think you're going to need something like this.
Edit: Here's one from Amazon. Double check how wide the ring is, though. The tool only goes down to a 5mm diameter.
I got a set like this Neewer Professional Spanner from Amazon, not great but worked well for me so far. Also used it on a few lenses with success.
