YouTube iframe shows forbidden error on blogspot page and webpage

Question

I am trying to show a youtube video on my webpage and Blogspot page using HTML iframe.

<iframe width="320" height="250" src="http://youtube.com/watch?v=Y4lqtiYLuJU"></iframe>

But it's giving me the following forbidden error :

This website does not permit its contents to be displayed in a frame, it must be opened in a new window.

I am getting the same error on Blogspot when posting this iframe code to my Blogspot page.

Is there any way to fix this?
