&_[:exports -html]{Watch [[https://youtube.com/...][Org mode in action

#+begin_export html
<iframe src="https://youtube.com/embed/...";

should be exported to HTML without the sentence with the link

<iframe src="https://youtube.com/embed/...";
 title="Org mode in action demo"
 width="..." height="..."></iframe>

however only the sentence with the link is exported to LaTeX or any 
other format
