RSS feed appears blank

I am trying to add a feed from this wordpress blog

http://kenyapage.net/football/comments/latest/

I am trying to add the feed to this page

http://kenyapage.net/football/comments/

I used the text below but the feed appears blank

<?php
include_once $_SERVER['DOCUMENT_ROOT'] . '/inc/simplepie.inc';
$feed = new SimplePie('http://kenyapage.net/football/comments/latest/');
?>

<h1><?php print $feed->get_title(); ?></h1>

<ul>
<?php foreach ($feed->get_items(0, 5) as $item): ?>

<li>
        <a>get_permalink(); ?>">
        <?php print $item->get_title(); ?></a>
    </li>
<?php endforeach; ?>
</ul>

I also uploaded simplepie.inc to the following folder
http://kenyapage.net/football/comments/inc

and also created a folder

http://kenyapage.net/football/comments/cache

Any ideas on why the feed is blank ?
The rest of the html is fine
