How do I delete photos from my shared photo stream on my iPhone6

[iMore Question]

the internal storage is almost maxed out. I have 1.38GB on my photo & camera. But my shared photo stream is showing 4KB and I am unable to find where to go to in order to delete them. My Photo Stream is showing 294 bytes, but I had thought I had already deleted that as well.

If I am not wrong, photo stream photos are not saved on phone's memory. Its saved on cloud. However, you can free up some space by deleting videos and photos from camera roll.
