Delete icons in "My connections" friends list items on the "Connections" page do not have alt text attributes and are the only content of a link. This creates a series of links with no text and are not useable to screen reader users. This prevents screen reader users from knowing they can delete connections.
Suggest adding an alt attribute to the <img src="/library/image/silk/delete.png"> tag that contains the friend's name:
<img src="/library/image/silk/delete.png" alt="Delete your connection to Bill Smith.">
