Youtube embed problem

In my blog there are over 100 posts with youtube iframe embed codes.

All the AMP pages with youtube iframe embed codes gives huge error instead of showing the page.

Example youtube iframe embed code taken from my blog post:

<iframe src="https://www.youtube.com/embed/uYlk4izYVmw?rel=0&showinfo=0" width="560" height="315" frameborder="0" allowfullscreen="allowfullscreen"></iframe>

Here you can see one of affected page with youtube embed code:

Please tell me how to fix this error?
