Show posts from current category and exclude current post

Hi,
how can I show X posts from current category and exclude current post?

this solution shows to me all posts from current category:

<?php
	global $post;
	$categories = get_the_category();

	foreach ($categories as $category) :?>

		<h3>More News From This Category</h3>
		<ul>

		<?php
			$posts = get_posts('numberposts=3&category='. $category->term_id);
			foreach($posts as $post) : ?>

			<li>
				<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
			</li>

		<?php endforeach; ?>

			<li><strong><a href="<?php echo get_category_link($category->term_id);?>" title="View all posts filed under <?php echo $category->name; ?>">ARCHIVE FOR '<?php echo $category->name; ?>' CATEGORY ?</a></strong></li>

<?php endforeach; ?>

		</ul>

But I need to exclude current post

thanks
