html5 nav element for multilanguage links

Should I include links to the same page on other languages inside nav?

Example (we are on Page1):

<nav>
<a href="page1">Page1</a>
<a href="page2">Page2</a>
<a href="page3">Page3</a>
<a href="page4">Page4</a>
<div class="flags">
<a href="/es/page1">Spanish</a>
<a href="/it/page1">Italian</a>
</div>
</nav>

Or it's better to put flags outside nav?
